Question 1010994: 32, 16, 8, 4, 2, ...
.
Find the common ratio of the given sequence, and write an exponential function which represents the sequence.

A)
2; f(x) = 32(2)x-1

B)

1/2; f(x) = 32x-1

C)
2; f(x) = 32(1/2)x-1

D)

1/2; f(x) = 32(1/2)x-1

the general formula for nth term of a geometric sequence is
Xn = ar^(n-1) where a is the first term, r is the common ratio
***************************************************************
in our problem a=32, r=(1/2)
Xn = 32(1/2)^(n-1)
I do not see any option that is correct
