Answer:
C. Divide a term by its preceeding term
Step-by-step explanation:
A geometric sequence is a sequence who has as common ratio. Meaning, you have to multiply a constant to each term to obtain the next term.
Given the geometric sequence: 3, 9, 27, ...
You can determine the common ratio by dividing a term by its preceeding term. For instance, 27 divided by 9 is 3, and 9 divided by 3 is aslo 3. We can therefore conclude that 3 is the common ratio of the geometric sequence.
