A geometric sequence is shown below. −12,−2,−8,−32,...
What is an explicit representation for the nth term of the sequence?
A. f(n)=12(−4)n
B. f(n)=−12(4)n−1
C. f(n)=−12(4)n
D. f(n)=12(−4)n−1

An explicit representation for the nth term of the sequence:

It means, option (B) should be true.

Step-by-step explanation:

Given the geometric sequence

A geometric sequence has a constant ratio, denoted by 'r', and is defined by

Determining the common ratios of all the adjacent terms

As the ratio is the same, so

r = 4

Given that f₁ = -1/2

substituting r = 4, and f₁ = -1/2 in the nth term

Thus, an explicit representation for the nth term of the sequence:

It means, option (B) should be true.

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest
