I see a geometric progression here
a=2
R=2
N=12
T12=2(2)^11=?
You finally get an allowance! You put $2. away in January, $4. away in February, $8. away in March, $16 away in April and followed this savings pattern through to December. How much money do you have in 12 months?

Or,
just continue grind out the pattern, you are already at April, just a few more
and you will get Isaac's answer.

n = the number of months.
Amount = 2^n * 2 = 2^3 * 2 = $16 after the 3rd month(March).
Amount = 2^12 * 2 = $8,192.
