Answer 2

Answer: 18

Step-by-step explanation:

this series is little tricky. there after arrangement of series it is written in randomly. so it may find difficult to solve but i am trying to explain the trick so that you can also understand.  

here is term is sum of last two terms.

so

3+4 = 7

7+4 =11

11+ 18 = 29

29+18 =47

29+47 = 76

so series will be 3, 4, 7, 11, 18, 29, 47, 76

after arrangement it written in random.

so

 3 4 7 76 11 47 29 ?

there is 18 is missing.  so 18 is answer.
