Question

Given the arithmetic sequence an = 2 − 3(n − 1), what is the domain for n?

Answer 1

First: what does n represent?

Answer 2

number of terms

Answer 3

Actually, n is a counter. Like counting on your fingers, it starts at 1 and increases by 1 each time: 1, 2, 3, 4, ...

So, what's the domain of n?

Answer 4

@mathmale i am confused

Answer 5

thats what mathway gave me but idk what that means

Answer 6

It wouldn't make sense if your counter, n, were negative. n must begin with 1 and increase by 1: 1, 2, 3, 4, 5, etc. So, which of the choices for the domain of n is correct?

Answer 7

All integers where n ≥ 1? @mathmale
