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?

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.

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