gains 0.2 every odd numbered month

gains 0.15 every even numbered month

write function for n months?

i've tried solving this with a formula, but every formula i come up with is wrong.

Could someone tell me how to solve this and plug in the right numbers into a formula?

**i already posted this but without the % for even numbered months. should there be two different formulas for even and odd months?

**Amy**, Monday, September 5, 2011 at 6:32pmFor the first five months algebrically i got:

1: 2400

2: 2040

3: 2448

4: 2080.8

5: 2496.96

i tried using this formula:

2000(1+0.2)^n

when i plugged in 1 for n i got 2400.

however, when i plugged in 2 for n i got 2880. which isn't right.

so i changed the formula to 2040(1+ .2)^1 I got the right answer

but is there a simple formula where i can just plug in the "n" and get the right amount?
