Question

3, 5,9,13, 21,..?..
1) 32
2) 30
3) 29
4) 25
explain​

Answer 1

dekho yaar

1 + 2 = 3

3 + 2 = 5

5 + 4 = 9

9 + 4 = 13

13 + 8 = 21

21 + 8 = 29

humne pehle 2 ko do baar add kiya

fir 2 +2 = 4 hote hain na

to 4 ko do baar add kiya

firse 4 + 4 = 8 hote hain to 8 ko do baar add kiya

to iske aage 29 aayega

aur 8 + 8 = 16 therefore

29 + 16 = 45

45 + 16 = 61

Series will be = 3, 5, 9, 13, 21, 29, 45, 61
