What should come in place of the question mark (?) in the given series?
22, 24, 28, 30, 34, ?

The correct answer is 36.

To find the missing number in the series, let us analyze the pattern of differences between consecutive terms:

First term to second term:
22 + 2 = 24

Second term to third term:
24 + 4 = 28

Third term to fourth term:
28 + 2 = 30

Fourth term to fifth term:
30 + 4 = 34

We can observe an alternating pattern of adding 2 and adding 4 (+2, +4, +2, +4, ...).

Following this pattern, the next operation should be adding 2 to the fifth term:
34 + 2 = 36

Therefore, the number that comes in place of the question mark (?) is 36.
