the series is the summation from n=1 to infinite of 12/(2)^n I know the series converges but I can't figure out the sum. I originally thought it was a pseries, but it's not and I am just stumped right now.

12( 1/2 +1/4  1/8 + ...) = 12([1/2]/[1+1/2]) = 4

so then would it be 12(1/2)^n or would it be... 12(1/2)^(n) and with that as a power series I could figure out the summation?
