Determine whether the sequence is geometric.
-$$- \frac { 1 } { 4 } , - \frac { 1 } { 9 } , - \frac { 1 } { 14 } , - \frac { 1 } { 19 } , \ldots$$
A) Geometric
B) Not geometric

Question

Quizplus · Accepted Answer

In a geometric sequence, each term is found by multiplying the previous term by a constant called the common ratio. Here, the sequence does not multiply by a constant ratio between terms, as the differences in the denominators are not consistent multiples of one another.
