C) 4, 12, 36, 108, . . .
D) 3, 12, 48, 192, . . .

C 4,12,36 108

Step-by-step explanation:

the answer is above.

C

Step-by-step explanation:

G.P= a,ar,ar^2,ar^3,...,

a1=4

a2=4×3=12

a3=4×9=36

a4=4×27=108

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
