Answer 2

Step-by-step explanation:

Let's take a look at series of differences

i. e. 2, 3,5,8 each term is expressed as addition of previous two terms…. Hence the series

2,3,5,8,13…and so on. The required series is obtained by adding the terms of series of differences.

e.g.

3+2=5

5+3=8

8+5=13

13+8=21

21+13=34

Hence 34 is the answer.
