Given the geometric sequence where a1 = 4 and the common ratio is 3, what is the domain for n?

Answer 1

Domain of a geometric or arithmetic sequence is the counting numbers unless otherwise noted.

Answer 2

Answer: Set of Natural numbers.

Explanation:

We know that the domain of a function is the set of all values for x for which the function must be defined.

The domain of the geometric sequence is always the set of natural numbers , since each term has a particular position in the sequence according to an order which can only represent by natural numbers.

Hence, the domain for the given geometric sequence = Set of natural numbers.
