# Math Help - Simplifying a Geometric Sequence

1. ## Simplifying a Geometric Sequence

If there's commands I could be using to make this look better, I'm sorry! Only about half of them are loading for me.

Simplify this:

A(sub)n = 64(1/2)^(n-1)

2. Do you mean like this?

$\displaystyle A_{n} = 64\left( \frac{1}{2}\right)^{n-1} = 64\frac{\left( \frac{1}{2}\right)^{n}}{\left( \frac{1}{2}\right)^{1}}$

Finish it off.
