Final answer:
A geometric sequence is a sequence of numbers in which each term is obtained by multiplying the previous term by a common ratio.
Step-by-step explanation:
A geometric sequence is a sequence of numbers in which each term is produced by multiplying the previous term by a common ratio. For example, the sequence 2, 4, 8, 16 is a geometric sequence because each term is obtained by multiplying the previous term by 2.
The correct answer is C) A sequence of numbers in which each term is produced by multiplying the previous term by a common ratio.
