Which explains why the graphs of geometric sequences are a series of unconnected points rather than a smooth curve?

A geometric sequence is defined for discrete term numbers such as 1, 2, 3, and so on, rather than for every value along a continuous interval. Its graph therefore has separate points at those natural-number inputs, not a smooth curve connecting them. The sequence’s terms do not have to be natural numbers, so choice D is not the reason.
