[tex]a_n=-4+4(n-1)\\\\n\in\mathbb{N^+}\\\\therefore\ the\ domain\ for\ n\ is\\\\\boxed{\text{All integers where}\ n\geq1}[/tex]

Answer:

All integers where n ≥ 1

Step-by-step explanation:

The domain of a relation represents the set of inputs, or x-values.

In a sequence, these inputs are the term numbers; that is, 1st term, 2nd term, 3rd term, etc.

These are called the 'counting' numbers; they are all integers starting at 1.  Therefore the domain is all integers where n ≥ 1 .
