NMMS - National Means-cum-Merit Scholarship Mental Ability: Number Series Questions and Answers

Question 1

Find the next number in the following series: 3, 7, 16, 35, ?

Accepted Answer

74

Answer

The pattern is to multiply the previous number by 2 and then add an increasing consecutive number. 3 x 2 + 1 = 7; 7 x 2 + 2 = 16; 16 x 2 + 3 = 35; Therefore, the next number is 35 x 2 + 4 = 74.

Question 2

A student is practicing for the NMMS exam and encounters the sequence: 8, 14, 26, 50. To maintain the pattern, which of the following numbers should come next?

Accepted Answer

98

Answer

The difference between consecutive numbers is doubling at each step. 14 - 8 = 6; 26 - 14 = 12; 50 - 26 = 24. The next difference should be 24 x 2 = 48. So, the next number is 50 + 48 = 98.

Question 3

Identify the missing term in the series: 121, 144, 169, ?, 225.

Accepted Answer

196

Answer

The series consists of squares of consecutive integers starting from 11. 11^2 = 121, 12^2 = 144, 13^2 = 169, 14^2 = 196, 15^2 = 225. The missing term is 196.

Question 4

Which of the following numbers would correctly replace the question mark in the series: 5, 6, 10, 19, 35, ?

Accepted Answer

60

Answer

The pattern involves adding the square of consecutive natural numbers, starting from 1, but with a twist. The differences are 1, 4, 9, 16, which are 1^2, 2^2, 3^2, 4^2. So, the next difference is 5^2 = 25. The next number is 35 + 25 = 60.

Question 5

A number series is presented as 4, 10, ?, 82, 244. Following the established pattern, what is the missing number?

Accepted Answer

28

Answer

The pattern is to multiply the previous number by 3 and then subtract 2. 4 x 3 - 2 = 10; 10 x 3 - 2 = 28; 28 x 3 - 2 = 82; 82 x 3 - 2 = 244. The missing number is 28.
