Question

The formula f(x + 1) = Two-thirds(f(x)) defines a geometric sequence where f(1) = 18. Which explicit formula can be used to model the same sequence?

f(x) = (18)(two-thirds)(x – 1)
f (x) = 18 (x minus 1) Superscript two-thirds
f (x) = 18 (two-thirds) Superscript x minus 1
f(x) = (18)x – 1

Answer 1

Correct!!!

C- f (x) = 18 (two-thirds) Superscript x minus 1

:)

Answer 2

Its C, f(x)=18[2/3]x-1
