22=13*2-4
39=22*2-5

Answer / brijesh
The wrong Number is 24.
Lets see how....
Given series of no. is.. 3, 5, 8, 13, 24, 39, 72
3*2-1 = 5
5*2-2 = 8
8*2-3 = 13
13*2-4= 22
22*2-5= 39
39*2-6= 72
So here we can see that 4th no. of serious will be 22 not 24.

Answer / karthikeyan
The wrong Answer is 39.
Bcoz
5-3=2 2 is a prime number
8-5=3 3 is a prime number
13-8=5 5 is a prime number
24-13=11 11 is a prime number
39-24=15 15 is not a prime number
So after 11 the next prime number is 17. If we are add 24
with 17 we will get 41. Then we sunstract 72-41=31 is the
prime number.
