Mensa Mensa IQ Numerical Pattern Recognition Questions and Answers 3 — Questions and Answers
Question 1: What number comes next in the series: 3, 6, 11, 18, 27, ?
- 35
- 36
- 38 (Correct answer)
- 40
Correct answer: 38
The differences are 3, 5, 7, 9, 11 — odd numbers increasing by 2, so 27 + 11 = 38.
Question 2: Find the missing number: 81, 27, 9, 3, ?
- 1 (Correct answer)
- 0
- 2
- 1/3
Correct answer: 1
Each term is divided by 3, so 3 ÷ 3 = 1.
Question 3: What is the next number: 2, 5, 11, 23, 47, ?
- 89
- 94
- 95 (Correct answer)
- 96
Correct answer: 95
Each term is doubled and then 1 is added: 47 × 2 + 1 = 95.
Question 4: Complete the pattern: 1, 4, 9, 16, 25, ?
- 30
- 36 (Correct answer)
- 49
- 35
Correct answer: 36
These are perfect squares (1², 2², 3², …), so the next is 6² = 36.
Question 5: What replaces the question mark: 7, 14, 28, 56, ?
- 96
- 108
- 112 (Correct answer)
- 120

- 44
- 45 (Correct answer)
- 46
- 47
Correct answer: 45
Differences are 9, 10, 11, 12, 13 — so 58 − 13 = 45.

- 18
- 20
- 21 (Correct answer)
- 22
Correct answer: 21
These are triangular numbers; differences increase by 1 each time, so 15 + 6 = 21.
