Given:
second term = 18
fifth term = 144
The nth term of a geometric sequence is:

Hence, we have:

Divide the expression for the fifth term by the expression for the second term:

Substituting the value of r into any of the expression:

Hence, the explicit rule for the sequence is:
Step-by-step explanation:

Answer:
factor is the answer
Step-by-step explanation:
I took the test
(12,-6) (4,-2)
4/12= 1/3
-2/-6= 1/3
the scale factor is 1/3
