A closed form is a simple equation that directly describes any element of a sequence without having to reference any other element or evaluate a sum.

For example, the closed form of f(n) = 1 + 2 + ... + n is f(n) = n(n+1)/2.

That answer you got doesn't make sense... Why would it ever write "1 - 1/3" instead of just "2/3"? There has to be an n in there somewhere... Maybe it's "1 - (1/3)ⁿ"?
