AON Inductive Reasoning 3

Question 1

What is the next number in the sequence: 5, 10, 20, 40, 80?

Accepted Answer

160

Answer

Each term is multiplied by 2, so 80×2=160.

Question 2

In the series 1, 3, 7, 13, 21, what is the next number?

Accepted Answer

31

Answer

The differences between terms are 2, 4, 6, 8, 10 (increasing by 2), so 21+10=31.

Question 3

What number is missing from the sequence: 2, __, 8, 14, 22?

Accepted Answer

4

Answer

The differences between terms increase by 2 each step (2, 4, 6, 8), so the missing number is 2+2=4.

Question 4

In the sequence 81, 27, 9, 3, what comes next?

Accepted Answer

1

Answer

Each term is divided by 3 (81÷3=27, 27÷3=9, 9÷3=3, 3÷3=1).

Question 5

Shapes follow this dot pattern: 1, 3, 6, 10 dots. How many dots does the next shape have?

Accepted Answer

15

Answer

These are triangular numbers where differences increase by 1 each time (2, 3, 4, 5), so 10+5=15.
