Find the 8th term of the geometric sequence –4, 12, –36, 108, –324,

pls mark me as brainliest

Step-by-step explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by

3

gives the next term. In other words,

a

n

=

a

1

⋅

r

n

−

1

.

Geometric Sequence:

r

=

3

This is the form of a geometric sequence.

Substitute in the values of

a

1

=

4

and

r

=

3

.

Remove parentheses.

=

⋅

n

−

Substitute in the value of

n

to find the

Subtract

Raise

3

to the power of
