Question

Given the arithmetic sequence an = 4 − 3(n − 1), what is the domain for n?

Answer 1

A. All integers where n ≥ 1
B. All integers where n > 1
C. All integers where n ≤ 4
D. All integers where n ≥ 4

Answer 2

hint:
generally, we can start to count from \(n=1\)

Answer 3

Do you have to plug in the integers?

Answer 4

I meant this, your sequence is composed by these quantities:
\[\huge {a_1},\;{a_2},\;{a_3},\;{a_4},...\]
so the littlest value of \(n\), is 1

Answer 5

Ah, so the domain has to be a positive value - equal or greater than 1?

Answer 6

that's right!

Answer 7

Great, thanks!
