I'm trying to find the common calculation between a series of numbers. For example:
I know that the calculation is simply the number squared. Another example would be:
In this example, I know that it is ((number * number) - 3) * number. So, with the number in the first set being 3, it would reduce down to ((3 * 3) - 3) * 3 = 18.
So, ultimately my question is trying to find the calculation between the following sets:
(for a bit of background as to why I'm asking this question, you can see my first failed attempt at asking the question here: Finding the calculation for the 24th permutation)
