The correct answer is:
The domain contains only natural numbers
.
Explanation:
The domain of a geometric sequence is the set of term numbers. This is the position of each term in the sequence: first, second, third, etc.
Since the domain is the set of positions, there are no decimal or fraction numbers in the domain. There would be no "2 and a half" term; it goes from the second to third.
This means that the values between the terms of the sequence have no value, and the graph will not be connected.
