Answer:
The set of all positive integers equal to or greater than 1
Step-by-step explanation:
n can take on the integer values 1 ... ∞
The formula for the nth term is a(n) = a(1) + 2(n - 1)
First term: n = 1. Then a(1) = 3 + 2(0) = 3 (as expected).
5th term: n = 5. Then a(5) = 3 + 2(5 - 1) = 3 + 8 = 11
...
and so on.
The domain for n in the given arithmetic sequence is the set of all positive numbers that are greater than or equal to one.
An arithmetic sequence is a sequence of numbers in which the difference between any consecutive is the same. This is known as the common difference.
The value of n for any arithmetic sequence can be any number that is positive and greater than 1. Therefore, we can say that the domain of the given arithmetic sequence is the set of all positive numbers greater than or equal to one.
Thus, the domain for n in the given arithmetic sequence is the set of all positive numbers greater than or equal to one.
