How to do a arithmetic sequence with roots using a loop
What I want to do is by using a for loop, calculate the sum of roots under roots (not a math guy, don't know how you call that).
The sequence should go like this:
Sqrt(2 + Sqrt(2 + ... + Sqrt(2))), where n > 0.
For example, if n = 3 on the for loop…
