Write an recursive formula for a_n and the n^th term of the sequence 3, -18, 108, If You answer this, you might become Brainliest

an=a1+(n-1)*-6

Step-by-step explanation:

a1= 3

the recursive formula is an= a1+ (n-1)d

d= how you get from one to the other

to get from 3 to -18 you could either subtract 21 or multiply it by -6

to find which one you have to look at the next number which is 108

to get from -18 to 108 you would either add 126 or multiply it by -6

since multiplying by -6 is in both that is the answer

d= -6

an=a1+(n-1)*-6

Answer and Step-by-step explanation:

First, we plug in the value of 3 for x in g(x), then we plug the answer os g(x) into the value of x in f(x).

g(3) = 2(3) - 7

Multiply 2 by 3, then subtract 7.

g(3) = 6 - 7

g(3) = -1

Now, we plug -1 for x in f(x).

f(g(3)) = f(-1) = -1 + 1

f(-1) = 0

The value of f(g(3)) is 0.
