Recursion and Iteration, part 1 of 2
And now... let's create the rule that describes a sequence! (crickets.) It doesn't have to be that way, because listing out terms based on a rule can be decoded in a way that makes total sense. The key to this whole maze is understanding in real terms what A(n), A(n+1) and A(n-1) actually mean. Once you do, these sequences and series will be yours for life. YAY MATH!
