Question

Use a recursive function for the geometric sequence 2, -6, 18, -54,... to represent the 9th term.

Answer 1

Answer:

The Answer is A. f(9) = f(8) • (−3)

Hope This Helps!

Answer 2

Answer:

f(9) = f(8)·(-3)

Step-by-step explanation:

A recursive function is one where each successive term is calculated using the previous term;

The clear pattern demonstrated in the sequence of terms shown is that each term is multiplied by -3 to give the next one;

Hence, the correct option is the first.
