The difference b/w each only prime numbers i, e; 2, 3, 5, 7, 11, 13, 17, 19, 23 etc, but in:
125+2=127.
127+3=130.
130+5=135.
135+7=142.
142+11=153.
153+13=166.
But 165 is not a correct. So select 169.
125+2=127.
127+3=130.
130+5=135.
135+7=142.
142+11=153.

The diffrence between each element: - 2 3 5 7 11 12
The diffrence between above series:- 1 2 3 4 1..............at last, it should be 5.
is this logic right which I applied?

Kanu we are adding prime nos successively like 2, 3, 5, 7, 11 and no shoud be 13 not 12, b'coz 12 is not a prime no thats why 165 is a wrong no.

Difference between successive numbers is in prime numbers increasing order such as 2, 3, 5, 7, 11, 13. Wrong number is 165.

All no are divisible by other nos but 127 is not divisible so it must be odd man out.

The number 127 is a prime so can also be treated as the odd one of the series
