I know a geometric expression can be written down as: $$ \sum_{k=1}^{n} ar^{k-1} = \frac{a(1-r^n)}{1-r} $$ Is it possible to solve this for r, knowing the total sum?

I am working on converting some python code over to Rust, and I have come across a bit of a peculiarity in the way that my code is behaving.
