The geometric sequence is given by:
an=ar^(n-1)
where:
a=first term
r=common ratio
n is the nth term
given that a=4, and second term is -12, then
r=-12/4=-3
hence the formula for this case will be:
an=4(-3)^(n-1)
where n≥1

Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is 
.
We need to find the factor of this trinomial.
The factors of is (x-2) and (x-8).
So, the factor of is (x-8). Hence, the correct option is (B).
