Isnt the $500 the first term?

Here is another problem I have, maybe it'll be easier to explain with another.

Suppose you deposit a nickel into your piggy bank on the first day of March and you double the previous day's deposit for every day until March 31. How much will be in the piggy bank at the end of the last day?

A) $53,687,091.15

B) $107,374,182.35

C) $214,748,364.75

D) $21,474,836.47

.05(1-2^30)/(1-2) =$53,687,091.15

Is that correct? Based off of that last one, I would guess this is wrong, but that looks right to me.
