## April 2018 Fiendish Function

The Fiendish Function posed during April 2018 had the following sample guesses and replies:

- 1
- 1
- 2
- -4
- 3
- -19
- 4
- -48
- 5
- -93
- 10
- 24

The rule was: "Cube the number, then subtract from two to the power of the number".

Suppose the guess was 11:

- Cube the number, giving 1331.
- Calculate two to the power of the number, giving 2048.
- Subtract the number from this, giving 717.

So the result is 717.
