Point out the odd one: 6, 9, 15, 21, 24, 28, 30?
- 24
- 21
- 28
- None of these
Explanation
- Looking at the series, we can see that the numbers are increasing with some common differences between them.
- The pattern is as follows:
- 6 + 3 = 9
- 9 + 6 = 15
- 15 + 6 = 21
- 21 + 3 = 24
- 24 + 4 = 28
- 28 + 2 = 30
By observing the pattern, we can see that all numbers follow an increment by either 3 or 6, except for 24, which increases by 4 instead of 3 or 6.
Therefore, the odd man out in the series is 24.
