CCAT - Criteria Cognitive Aptitude Number Series Patterns Questions and Answers 1 — Questions and Answers
Question 1: What is the next number in the following series? 4, 6, 10, 16, 24, ...
- 32
- 34 (Correct answer)
- 30
- 36
Correct answer: 34
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, ...
- 1 (Correct answer)
- 1/3
- 0
- 3
Correct answer: 1
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, ...
- 11
- 8
- 12 (Correct answer)
- 13
Correct answer: 12
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, ...
- 16 (Correct answer)
- 81
- 32
- 24
Correct answer: 16
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, ...
- 35
- 49
- 36 (Correct answer)
- 42
Correct answer: 36
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.
Question 6: Which number logically follows this series? 3, 7, 10, 17, 27, ...
- 37
- 40
- 44 (Correct answer)
- 47
Correct answer: 44
This is a Fibonacci-style sequence where each number is the sum of the two preceding numbers. 3 + 7 = 10; 7 + 10 = 17; 10 + 17 = 27. The next number is 17 + 27 = 44.
