AON Inductive Reasoning 1

Question 1

What number comes next in the sequence: 3, 7, 15, 31, 63?

Accepted Answer

127

Answer

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?

Accepted Answer

37

Answer

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?

Accepted Answer

Q

Answer

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?

Accepted Answer

17

Answer

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?

Accepted Answer

11

Answer

Each shape adds 2 sides to the previous (3, 5, 7, 9, 11), so Shape 5 has 11 sides.
