nth term of A.P. given by an = a+ (n-1)d
Sum of n terms of an AP
Sn = n/2 {2a + (n-1) d} or n/2 {first term + last term}
Arithmetic mean is (a+ an)/2.
Here, a is the first term, d (=a2- a1) is a common difference and n is the number of terms in AP.
nth term of the G.P. is an = ar(n-1)
Sum of n terms of a GP
Sn = a{(1- rn)/(1-r)}
sum of an infinite G.P. is given by
S = a/1-r
Geometric Mean of a & b is (ab)1/2.
Here, a is the first term, r (=a2/a1) is the common ratio and n are numbers of terms in GP.
Harmonic Progression (HP)
If a, b, c are in AP, then 1/a, 1/b, 1/c are in HP.
Solve HP with the help of AP.
Q1. Sequence and Series Questions for CAT Exam are given below:
Three positive integers x, y and z are in arithmetic progression. If y − x > 2 and xyz = 5(x + y + z), then z − x equals [CAT 2021, slot 2]
Sequence and series questions and answers are given below:
Solution: [3]
If x, y and z are in AP, then
y- x = z- y > 2 (Given)
So, y > x +2 and z > y+ 2; z > x+ 4
Also, x+ z = 2y
It is given that
xyz = 5(x + y + z)
⇒ xyz = 5(3y)
⇒ xz = 15 and z > x+ 4
If z = 15, x = 1 (z > x+ 4, true)
If z = 5, x =3 (z > x+ 4, false)
Therefore z =15 and x= 1 will be taken and the difference is 14.
Q2. Sequence and Series Questions for CAT are given below:
For a sequence of real numbers x1, x2, ..., xn, if x1 - x2 + x3 - ... + (-1)n + 1xn = n2 + 2n for all natural numbers n, then the sum x49 + x50 equals [CAT 2021, Slot 2]
CAT questions on sequence and series are given below:
Answer: [2]
Sn = if x1 - x2+ x3 - ... + (-1)n + 1xn = n2 + 2n
If n = 50; S50 = 502+ 2 x 50 = 2600 = x1 - x2 + x3 - ... + x49 -x50
S49 = 492+ 2 x 49 = 2499 = x1 - x2 + x3 - ... + x49
So, S50 = S49 - x50
⇒ x50 = S49 - S50 = 2499 – 2600 = -101
S48 = 482+ 2 x 48 = 2400
Similarly, x49 = S49 – S48 = 2499 – 2400 = 99
So, x49 + x50 = -101 + 99 = -2

CAT 2024 Syllabus Topic: Strategy to prepare “Picking of Coins” for CAT
Important Concept/Formula Used in questions on coins
These problems are basically a special type of D.I. problems which require a high level of understanding.
There are basically two types of scenarios in these Questions.
The first case is who picks last wins the game
Second case is who picks last loses the gam
For the first case, the person who picks last wins must left (MINIMUM PICK +MAXIMUM PICK) *k coins on the table to ensure it wins.
In the second case, the person who picks last loses. So, the person who picks first must left(MINIMUM PICK +MAXIMUM PICK) *k+ 1) coins on the table to ensure it’s winning.
Q1. Two smart players A and B are playing a coin game in which they can pick up 1, 2, 3, or 4 coins. They have 78 coins and the player who picks the last coin will lose the game. A and B play alternately and A plays the first move. How many coins should A pick at first so his win is independent of the number of coins B picks in his first move?
[CAT PYQ]
Solution:
As the question explained, A is the first picker so he needs to maintain a such number of coins on the table that after his first pick his winning doesn't depend on the coins picked up by B.
So, in such cases, the trick is to maintain (multiple of a sum of minimum pick + maximum pick on the table)
So, the person who has the chance to pick first must pick as many numbers of coins so on the table the coins left on the table must be
(Multiple of the sum of minimum pick + maximum pick on the table)
So if this question the sum of minimum pick + maximum pick would be (1+4)k=5k
must leave on the table so the first person will pick 3 coins from the table and left 75 coins on the table for another person so he will ensure his win.
Q2. An old woman had the following assets: [CAT 2017]
Rs. 70 lakh in bank deposits
1 house worth Rs. 50 lakh
3 flats, each worth Rs. 30 lakh
a certain number of gold coins, each worth Rs. 1 lakh
She wanted to distribute her assets among her three children; Neeta, Seeta and Geeta. The house, any of the flats or any of the coins were not to be split. That is, the house went entirely to one child; a flat went to one child and similarly, a gold coin went to one child.
The value of the assets distributed among Neeta, Seeta and Geeta were in the ratio of 1:2:3, while the gold coins were distributed among them in the ratio of 2:3:4. One child got all three flats and she did not get the house. One child, other than Geeta, got Rs. 30 lakh in bank deposits.
How many gold coins did the old woman have?
Ans: [B]
Let the old woman have ‘x’ gold coins.
herefore, total asset base = Rs. 70 lakhs + Rs. 50 lakhs + Rs. 3 * 30 lakhs + x = Rs 210 lakhs + x
The assets were distributed in the ratio of 1:2:3. So, 210 +x should be multiple of 6.
Since there are “x” gold coins, then the total 210 + x is a multiple of 6.
210 is a multiple of 6. So, x is a multiple of 6.
Also, the gold coins were distributed in the ratio of 2:3:4. So, gold coins should be multiple of 9 also. Therefore, from the above two conclusions, we can say that gold coins are multiple of 18.
Therefore, x is a multiple of 18.
The total value of assets can be taken as 210 + 18k.
Dividing this in the ratio of 1:2:3 among Neeta, Seeta and Geeta.
Neeta = 1/6 x (210 + 18K) = 35 + 3k = 35 – k + 4k
Seeta gets = 2/6 x (210 + 18K) = 70 + 6k
Geeta gets = 3/6 x (210 + 18K) = 105 + 9k = 105+ k + 8k
Discuss for Geeta, the one only who can get three flats worth Rs 90 lakhs
Geeta will have a house of worth Rs 50 lakh, So, she cannot get Rs 30 lakh Cash.
Neeta will get 30 lakhs bank deposits, she will get (5+ 3k) gold coins.
Neeta got a total (35 – k) + 4k worth of assets. So, k = 5.
Neeta = 30 lakhs deposit and 20 gold coins
Seeta = One house + Rs. 20 lakh in bank deposits + 30 gold coins.
Geeta = 3 flats + Rs. 20 lakh in bank deposits + 40 gold coins.
Therefore, the total no. of gold coins = 20 + 30 + 40 = 90.
Tips/Tricks for CAT questions on coins
These are special types of problems, so these must be practised before exams.
All different types of cases needed to be covered by aspirants because every case required a unique approach to solve this question.

CAT Exam Important Topic: Strategy to Prepare “Statement and Arguments” (What is Critical Reasoning in CAT) for CAT-2024
Important Concept used in Statement and Arguments questions
Q1. Statements and Arguments are given below:
Statement: Should military training be made compulsory in our country? [PYQ]
Arguments:
1. Yes, every child should go through this training
2. No, it is not compulsory in USA
If only argument I is strong.
If only argument II is strong.
If either I or II is strong.
If neither I nor II is strong.
If both I and II are strong.
Statements and Arguments questions with solutions are given below:
Ans. Option D
Explanation:
Argument 1: Not every child is strong enough physically. So, it is not a strong argument.
Argument 2: USA is a different country at different levels. Comparison is done here so it is also a weak argument.
Q2. Statements and Arguments (critical reasoning questions for CAT) are given below:
Statement: Should powerful nations attack relatively weaker nations which pose a probable danger to world peace? [IPMAT 2020]
Arguments:
Yes. War is justified for the noble purpose of peacekeeping.
No. War/violence should never be resorted to.
If only 1 is implicit
If only 2 is implicit
If either assumption 1 or 2 is implicit
If neither assumption 1 nor 2 is implicit
Ans: [A]
Explanation:
If someone is dangerous to humankind, it should get eliminated by a stronger person. So, Argument I seem to be implicit.
Tips and Tricks for CAT questions on Statement and Arguments
The criterion of being either true or false is one thing that served to identify the informative use of language.
An argument is a set of at least two statements, one of which is the conclusion of the argument, and the rest of which are premises offered in support of the conclusion.
An argument will often contain indicator words that help identify the premises and conclusion.
Some conclusion indicators are:
So/, therefore,/consequently/ as a result/thus/hence/accordingly/it follows that
Some Premise indicators are:
Since/because/for/in light of/in view of/as shown by.
Identify strong arguments and weak arguments
Strong Arguments Includes:
Facts based on experience
Educational development
Universal truth etc
Weak Arguments Include:
over exaggeration
Involves Comparison
Half explained arguments
Contains words like Each, Nothing, Very, All, only etc
