Question 4 • CA-Mathematics I
The formula f(x + 1) = (f(x)) defines a geometric sequence where f(1) = 18. Which explicit formula can be used to model the same sequence?
Answer
A
f(x) = (18)(x – 1)
B
f (x) = 18 (x minus 1) Superscript two-thirds
C
f (x) = 18 (two-thirds) Superscript x minus 1
D
f(x) = (18)x – 1
