To be clear 12 is not a prime number because it is divisible by 9 and 1. Prime number is only divisible by 1 and it should not be multiple of any other number.

The series can follow 2, 5, 2, 5 (these being the difference between the two numbers).
So the series will be like 3 5 10 12 17 19. So 7 is the odd one out.

The remainder for every other number is 1 except 12 hence 12 is the odd one.
3/2 = 1
5/2 = 1
7/2 = 1
12/2 = 0 this is right
17/2 = 1
19 / 2 = 1

3+5 =7
7+5 =12
12+7= 19
Thus if form Fibbonaci series then odd one in series is 12 . 12 also be the answer.
