Question

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

All integers
All integers where n ≥ 0
All integers where n ≥ 1
All integers where n > 1

Answer 1

Answer 2

\(a_n=-4+4(n-1)\)
^this is the given expression for the arithmetic sequence

the domain is nothing but all the values that \(n\) can take

here n denotes the \(n^{th}\) term of the sequence

and in a sequence the terms are like-> 1st term( for n=1), 2nd term(for n=2), 3rd term and so on
so we don't have any thing like" -1st term" or "-2nd term" or "0th term"

now try to find out the answer =]

Answer 3

so C ?

Answer 4

yeah =]
