Question

Given the geometric sequence where a1 = 3 and the common ratio is −1, what is the domain for n?

Answer 1

Answer:

The domain for n is:

All integers where n ≥ 1

Step-by-step explanation:

We are given a geometric sequence where the first term of the sequence is:

$a_1=3$ and the common ratio(r) is −1.

We are asked to find the domain for n.

We know that the domain of the geometric sequence whose terms are given by $a_n$ are all the natural numbers since by putting the n we get the corresponding term.

Hence, the domain is:

All integers where n ≥ 1

Answer 2

All integres n >= 1

Its D
