Answer:

Option: B is the correct answer.

B. All integers where n ≥ 1

Step-by-step explanation:

An arithmetic sequence is a sequence in which each term after the first term is obtained by adding a fixed number, the common difference, to the previous term.

So, the domain of the arithmetic sequence is the set of possible values at which it is defined.

Now,

we are given an arithmetic sequence as:

Now, the domain is:

B. All integers where n ≥ 1  

( Since the terms are the first term, second term, third term, and so on)
