Answer:
an = 3+3(n-1)
Step-by-step explanation:
We are adding 3 each time
6-3 = 3 9-6 = 3
The common difference is 3
The explicit formula for an arithmetic sequence is
an = a1+d(n-1)
The first term is a1 = 3
d =3
See attached picture
b c and f edit: also A
just gotta find what is reflexive
x = 6
8x = 48,
Divide each side by 8 to isolate x
8x/8 = 48/8
