Given the geometric sequence where a1 = 2 and the common ratio is 8, what is the domain for n?

a. all integers

b. all integers where n ≥ 1

c. all integers where n ≥ 0

d. all integers where n ≥ −1

B. All integers where n ≥ 1

Step-by-step explanation:

We are given the geometric sequence where a1 = 2 and the common ratio is 8.

Where a1 is the first term.

we have to find the domain for n.

The general formula for the geometric sequence is:

Clearly, n can take any integer value n≥1

Hence, the correct option is:

B. All integers where n ≥ 1
