Cain · Answer 1

The domain is all integers where n is greater than or equal to 1.

Explanation:

Since this is a sequence, n represents the term number, which is the position in the sequence. We start counting terms of a sequence beginning with term #1, and continue using integers; this means the domain will be all integers greater than or equal to 1.
