Question

In the following number series, only one number is wrong. Find out that number:

0, 7, 28, 63, 124, 215

Options

• 7

• 63

• 28

• 215

Answer 1

28

Explanation:

The pattern is as follows:

1³ - 1 = 0

2³ - 1 = 7

3³ - 1 = 26

4³ - 1 = 63

5³ - 1 = 124

6³ - 1 = 215

Hence, the wrong number in the series is 28.
