i have figured out on my calculator what the answer is but the answer wont work when i use a formula.. HELP

WIth first term of 100, common factor of 2 and number of years n = 15,
S = 100(2^15  1)/(2  1) =
or (100+200+400+800+16oo+3200+6400+12800+25600+51200+102400+204800+409800+819200+1638400)100 =
