5, 8, 13, 20, 29,?, 53, 68, 85

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 40.

Understanding

Given series: 5, 8, 13, 20, 29,?, 53, 68, 85.

The logic used here is:

5 + 3 = 8

8 + 5 = 13

13 + 7 = 20

20 + 9 = 29

29 + 11 = 40

40 + 13 = 53

53 + 15 = 68

68 + 17 = 85

The next term in the series is 40.

Hence, option 1 is the correct answer.
