Given the arithmetic sequence an = 5 + 2(n − 1), what is the domain for n?

all integers
all integers where n ≥ 0
all integers where n > 1
all integers where n ≥ 1

someone me. you.

The domain for n is:

            All integers where n ≥ 1

We know that the domain is the collection of all the possible input values i.e. for which the function or sequence is well defined.

The arithmetic sequence is given by:

We know that the terms of the sequence is given by:

i.e. first term, second term and third term and so on.

Hence, n=1 i.e. it starts with the first term of the sequence.

                Hence, the answer is:

                All integers where n ≥ 1
