Question

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

Answer 1

Answer:

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:

  $an=a1\times r^{n-1}$

Clearly, n can take any integer value n≥1

Hence, the correct option is:

B. All integers where n ≥ 1
