What is the first term and explicit rule for the following geometric sequence? 3. 15,75,375, 1,875

First term: 3

Exiplicit formula:

or 3x5^n-1

Hope this helps!

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
