A new after-school club has 4 times as many members each month as it did the month before. If you list the number of members each month, what kind of sequence will you see?

Question

A) arithmetic
B) geometric
C) both
D) neither

Answer 1

If the number of members in the after-school club each month increases to 4 times the number it had the previous month, this describes a geometric sequence. In a geometric sequence, each term is found by multiplying the previous term by a fixed ratio (in this case, 4).

Thus, the answer is: B) geometric
