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 series is 3,5,8,13,22,39,72 24 should be replaced by 22 24 is wrong……. Reply
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. Reply
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 series is 3,5,8,13,22,39,72

24 is wrong…….
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.
