Select the number that can replace the question mark (?) in the following series?1, 2, 4, 7, 13, 24, 44, ?1. 812. 633. 1124. 73

Answer» Correct Answer - Option 1 : 81

Logic : To get the next term in the series add previous two terms.

The pattern followed here is :

1 + 1 = 2

2 + 1 + 1 = 4

4 + 2 + 1 = 7

7 + 4 + 2 = 13

13 + 7 + 4 = 24

24 + 13 + 7 = 44

44 + 24 + 13 = 81

Hence, '81' is the correct answer.
