Enter the explicit rule for the geometric sequence. 120, 40, 40/3, 40/9, 40/27,  i know the first part would be but i dont know what would be put in the middle of the parenthesis so if anyone could that would be awesome ty! an= 120( )^n-1

Step-by-step explanation:

The given geometric sequence is 120, 40, 40/3, 40/9.........n terms.

As we know nth term of a geometric sequence is represented as

Here a(n) = nth term

a = first term

r = common ratio

n = number of terms

In this sequence a = 120

r = second term/first term = 40/120 = 1/3

Therefore the sequence can be represented as

Explicit rule of the geometric sequence is

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
