Can you give us a hint?

Is it strictly numeric/mathematical?

Or does it involve some social thing?

Something about some products?

I know it is tough!!! But it is mathematical......KenJacksonCan you give us a hint?

Hint: Every number is dependent only on its previous number, except the 1st one(Ex: 62 is derived only from 72).

Also, sometimes there might be many answers for a series. thinking might be different!!! I would be happy to have any answer with a proper explanation.

Ans is 132 according to my logic...

7^2+2^2+7+2=62...

6^2+2^2+6+2=48...

4^2+8^2+4+8=92...

9^2+2^2+9+2=96...

7^2+2^2+7+2=62...

6^2+2^2+6+2=48...

4^2+8^2+4+8=92...

9^2+2^2+9+2=96...

**9^2+6^2+9+6=132.**..Prashanth_p@cchi · Jun 12, 2012

OK, that explains why they're all even numbers.

An odd numbered squared is always odd, and the sum of two odd numbers is always even.
