Seems to be a geometric sequence which is found by

an=nth term
a1=first term
r=common ratio
first term is 0.75
it doubles each time so common ratio is 2

to find the nth term, input n and evaluate
example
to find the 20th term




just to find the kth term, input k for n in
Answer: B: 2.87
The percent formula is Y = P% * X
Y = 2.87% * 3204
p = 2.87/100 = 0.0287
Y = 0.0287 * 3204
Y = 91.9548 (Closest Answer)
It is the second function:
y=(1/2)^(x-3)
When x=0, the exponent is -3. (1/2)^-3 is 8.
y = 8+1 = 9
