All integers where n ≥ 1.
We have given that the sequence,
[tex]a_{n} =4-3(n-1)[/tex]
We have to find the domain for n.
What is the meaning of arithmetic sequence?
Arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. Difference here means the second minus the first.
That is, [tex]a_{n} =a+(n-1)d[/tex]
where a = first term of sequence.
d =common difference.
n =number of terms which belongs to natural numbers
By the definition of arithmetic sequence n starts with 1
Remember that,the natural number starts with 1
Now, in given sequence for nth term
[tex]a_{n} =4-3(n-1)[/tex]
The domain for n is All integers where n ≥ 1.
