In a rectangular triangle
.
We have 
Therefore opposite = 3uints and adjacent = 4units.

We need the length of hypotenuse.
Use the Pythagorean theorem:

Substitute:

The next number in the given series is going to be 565.
2, 3, 8, 27, 112, ?
2 * 1 + 1 = 3
3 * 2 + 2 = 8
8 * 3 + 3 = 27
27 * 4 + 4 = 112
112 * 5 + 5 = 565.
Good luck :)
