Question

Write a function to represent the geometric sequence 6, 18, 54, .... (1 point)
f(x) = 3(6)*-1

O f(x)=6(3)*-1

• f(x) =3(6)*

O f(x)=6(3)*

Answer 1

The common ratio is 3 and the first term is 6, so the nth term is
f(n) = 6·3^(n−1).
(If you label terms starting at n = 0, use f(n) = 6·3^n.)
