A sequence is called a sequence if the ratios of consecutive terms are the same. This ratio is called the ratio. |
| Type of Sequence | Description |
|---|---|
| arithmetic sequence | A sequence is arithmetic when the differences between consecutive terms are the same. This difference is the common difference of the sequence. |
| geometric sequence | A sequence is geometric when the ratios of consecutive terms are the same. This ratio is the common ratio of the sequence. |
We can see that the given sentence matches the description of the geometric sequence. With this in mind, let's complete the sentence.
