Consider the geometric sequence: 1, 3, 9, 27, ... if n is an integer, which of these functions generate the sequence?
a) a(n)=3^n for n greater than or equal to 0
b) b(n)=3(3)^n for n greater than or equal to 0
c) c(n)=3^n for n greater than or equal to 2
d) d(n)=3^n-1 for n greater than or equal to 2

PLS ANSWER ASAPP!!

Step-by-step explanation:

Since the sequence is a geometric sequence

For an nth term in a geometric sequence

where

n is the number of terms

a is the first term

r is the common ratio

To find n we must first find the common ratio

To find the common ratio divide the previous term by the next term

That's

r = 3/1 = 3 or r = 9/3 = 3

a = 1

Substitute the values into the above formula

That's

If n is an integer then

where n is greater than or equal to 2
