Answer:
In a geometric sequence, the common ratio between consecutive terms is constant.
Step-by-step explanation:
In a geometric sequence, the common ratio between consecutive terms is constant.
The n-th term of a geometric sequence with first term
and common ratio
is represented by the formula:

For example,

As the common ratio 'r' between consecutive terms is constant.
So, the common ratio between consecutive terms is constant i.e. -3. Thus, it is a geometric sequence with a common ratio -3.
