AMM Problem 12510 Solution

On a limit with nested radicals

In this article, I provide a solution to AMM Problem 12510.
The problem is an interesting limit of the sum of product of nested square roots. The question looks really tricky and convoluted until it decoposes into a series of recurrence relations that can be combined for the solution and proving it rigorously.
It felt like I just needed to take small steps and uncover small relations that combined into an interesting form!

I hope you enjoyed reading the article
