CCAT - Criteria Cognitive Aptitude Number Series Patterns Questions and Answers

Question 1

What is the next number in the following series? 4, 6, 10, 16, 24, ...

Accepted Answer

34

Answer

The pattern involves adding a progressively increasing even number to each term. The differences between consecutive numbers are +2, +4, +6, +8. The next difference should be +10. Therefore, 24 + 10 = 34.

Question 2

Which number should come next in this series? 81, 27, 9, 3, ...

Accepted Answer

1

Answer

This is a geometric progression where each number is divided by 3 to get the next number in the series. 81 / 3 = 27, 27 / 3 = 9, 9 / 3 = 3, and finally 3 / 3 = 1.

Question 3

Find the next number in the sequence: 5, 8, 7, 10, 9, ...

Accepted Answer

12

Answer

This series follows an alternating pattern of adding 3 and then subtracting 1. 5 + 3 = 8; 8 - 1 = 7; 7 + 3 = 10; 10 - 1 = 9. The next step is to add 3, so 9 + 3 = 12.

Question 4

What is the next number in the following series? 2, 3, 4, 9, 8, 27, ...

Accepted Answer

16

Answer

This question features two interleaved series. The first series consists of powers of 2 (2, 4, 8, ...) and the second series consists of powers of 3 (3, 9, 27, ...). The next number belongs to the first series, which is 2^4 = 16.

Question 5

Identify the next number in the sequence: 1, 4, 9, 16, 25, ...

Accepted Answer

36

Answer

The series consists of perfect squares of consecutive integers. 1^2 = 1, 2^2 = 4, 3^2 = 9, 4^2 = 16, 5^2 = 25. The next number is 6^2, which is 36.
