Happy December, everyone, and thanks for playing the Wednesday Brain GameWhat's the next number in the following sequence (and why)?

1, 13, 41, 85, 145, ?

Here is the SOLUTION.

SOLUTION:

221.

The numbers represent the following:

o² + 1² = 1
2² + 3² = 13
4² + 5² = 41
6² + 7² = 85
8² + 9² = 145
so...

10² + 11² = 221
