Answer 2

Answer:15131

Step-by-step explanation:

In this question the series given is

1 3 11 123....

If you notice keenly the first no is 1,the next one is 3 which is 1*1+2=3

The next one is 3*3+2=11.

Followed by 11*11+2=123

The current term is getting squared and then added two to it.

Hence, 123*123+2= 15131
