Answer:
Domain of a geometric or arithmetic sequence is the counting numbers unless otherwise noted.
Answer: Set of Natural numbers.
Step-by-step 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.
