Use a recursive function for the geometric sequence 2, -6, 18, -54,... to represent the 9th term. f(9) = f(8) • (-3)

f(9) = f(1) • (-3)^8

f(9) = f(1) + -3(8)

f(9) = f(8) + -3(8)

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.

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
