AON Inductive Reasoning 1 — Questions and Answers
Question 1: What number comes next in the sequence: 3, 7, 15, 31, 63?
- 95
- 127 (Correct answer)
- 111
- 99
Correct answer: 127
Each term is calculated by doubling the previous term and adding 1 (×2+1), so 63×2+1=127.
Question 2: In the series 2, 5, 10, 17, 26, what is the next number?
- 35
- 36
- 37 (Correct answer)
- 38
Correct answer: 37
The differences between consecutive terms are 3, 5, 7, 9, 11 (increasing by 2), so 26+11=37.
Question 3: Which letter continues the series: B, E, H, K, N?
- O
- P
- Q (Correct answer)
- R
Correct answer: Q
Each letter advances 3 positions in the alphabet (B+3=E, E+3=H, H+3=K, K+3=N, N+3=Q).
Question 4: Which number does NOT belong in the set: 4, 8, 12, 17, 20, 24?
- 8
- 12
- 17 (Correct answer)
- 20
Correct answer: 17
All other numbers are multiples of 4, but 17 is not divisible by 4.
Question 5: If Shape 1 has 3 sides, Shape 2 has 5 sides, Shape 3 has 7 sides, how many sides does Shape 5 have?
- 9
- 10
- 11 (Correct answer)
- 13
Correct answer: 11
Each shape adds 2 sides to the previous (3, 5, 7, 9, 11), so Shape 5 has 11 sides.
Question 6: In the series Z, X, V, T, what letter comes next?
- R (Correct answer)
- S
- Q
- P
Correct answer: R
The series moves backward through the alphabet, skipping one letter each time (Z→X→V→T→R).
Question 7: What pattern rule applies to the pairs (2,4), (3,9), (4,16), (5,25)?
- The second number is twice the first
- The second number is the square of the first (Correct answer)
- The difference between the numbers increases by 2
- Both numbers are always even
Correct answer: The second number is the square of the first
In each pair, the second number equals the first number squared (2²=4, 3²=9, 4²=16, 5²=25).
