Question 6 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY

Which graph represents a geometric sequence?

Answer

Image with description On a coordinate plane, 3 points are plotted. The points are (1 comma 2), (4 comma 4), (9 comma 6).

Image with description On a coordinate plane, 4 points are plotted. The points are (1 comma 1), (2 comma 2), (3 comma 4), (4 comma 8).

Image with description On a coordinate plane, 5 points are plotted. The points are (1 comma 1), (2 comma 3), (3 comma 5), (4 comma 7), (5 comma 9).

Image with description On a coordinate plane, 3 points are plotted. The points are (1 comma 1), (2 comma 4), (3 comma 9).

Explanation

A geometric sequence has the same ratio between each pair of consecutive terms. In choice D, the y-values are 1, 2, 4, and 8; each term is twice the one before it, so the common ratio is 2. The other choices do not have a constant ratio between consecutive y-values.
