CFAT Problem Solving: Logical Reasoning 3 — Questions and Answers
Question 1: What comes next in the sequence: 3, 6, 12, 24, ___?
- 36
- 42
- 48 (Correct answer)
- 30
Correct answer: 48
Each term is doubled: 3×2=6, 6×2=12, 12×2=24, 24×2=48.
Question 2: Find the missing number: 2, 5, 10, 17, 26, ___
- 35
- 37 (Correct answer)
- 36
- 38
Correct answer: 37
The differences increase by 2 each time (+3,+5,+7,+9,+11), so 26+11=37.
Question 3: What letter comes next: A, C, F, J, O, ___?
- U (Correct answer)
- T
- V
- W
Correct answer: U
The gaps increase by one each step: +2, +3, +4, +5, +6; O is the 15th letter, and 15+6=21=U.
Question 4: Which number is next in the sequence: 100, 91, 83, 76, 70, ___?
- 65 (Correct answer)
- 63
- 64
- 66
Correct answer: 65
The decrements shrink by one each step: −9,−8,−7,−6,−5, so 70−5=65.
Question 5: Which number does NOT belong in this sequence: 7, 11, 15, 19, 22, 27?
- 7
- 15
- 22 (Correct answer)
- 27
Correct answer: 22
The sequence increases by +4 each time (7,11,15,19,23,27), so 22 is incorrect — it should be 23.

Each term is the sum of the two preceding terms (Fibonacci): 13+21=34.
Question 7: Complete the series: 1, 4, 9, 16, 25, ___
- 36 (Correct answer)
- 30
- 34
- 38
Correct answer: 36
These are perfect squares: 1²,2²,3²,4²,5²,6²=36.
