Given the arithmetic sequence a_n = -3 + 9(n - 1), what is the domain for n?

Solution:

The arithmetic sequence formula is used for the calculation of the nth term of an arithmetic progression.

The arithmetic sequence is the sequence where the common difference remains constant between any two successive terms.

It is given that a_n = -3 + 9(n - 1)

Which is an arithmetic sequence

We know that

The domain of a function is a complete set of all the possible values of n

We can take the value of n: 1 and greater than 1

Here the set of the domain for n is written as {n ∈ N: n ≥ 1}

Therefore, the domain for n is {n ∈ N: n ≥ 1}.

Given the arithmetic sequence a_n = -3 + 9(n - 1), what is the domain for n?

Summary:

Given the arithmetic sequence a_n = -3 + 9(n - 1), the domain for n is {n ∈ N: n ≥ 1}.
