Question

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

Answer 1

Answer:

The domain for n i all integers where n ≥ 1  Option D.

Step-by-step explanation:

The sequence n is a natural number  

We have to find out domain.  

For any function, y = f(x) domain is a set, in which function y is defined. In some way you can say that all value of x in which function is defined is known as domain.  

Here  

Domain ∈ Natural number or n ≥ 1

Where, ∈ - the symbol belongs to

That is, domain belong to Natural number or n ≥ 1
