Put on your mathematical thinking cap and take the Tuesday Test Time challenge for today's mentalfloss.com Brain Game. Good luck!

What's the next number in the following series? 1, 2, 2, 4, 8, 12, 96, 108, ?

Here is the SOLUTION.

THE SOLUTION:

10,368.

The pattern for successive numbers alternates between multiplication and addition:

1 × 2 = 2
2 + 2 = 4
2 × 4 = 8
4 + 8 = 12
8 × 12 = 96
12 + 96 = 108
96 × 108 = 10,368

Thanks for playing! Tomorrow, it's Wordplay Wednesday.
