Question 1109516: My Alegbra Mid term study guide has stumped me on this one question which is probably very simple I just haven't been in class. It says which shows a function for the sequence 16, 8, 4, 2...? The list of answers are ;
A. f(x) = 16 � (2)^x-1
B. f(x) = 16 (1/3)^x -1
C. f(x) = 16 � (1/2)^x-1
D. f(x) = 16 � (1/4)^x-1
