Answer:
Step-by-step explanation:
The common ratio of a geometric sequence can be found dividing the current term in the sequence by the previous term in the sequence. In other words, where:
is the common ratio of the geometric sequence
is the current term in the sequence
is the previous term in the sequence
- For and
- For and
Since the ratio is the same for both pair of number in the geometric sequence, we can conclude that 5 is the common ratio of the sequence.
