Question

Find the common ratio of the geometric sequence 11,-55,275

Answer 1

The answer is - 5

Explanation:

To find the common ratio of a given sequence , divide the previous term by the next term

We have

`r = - (55)/(11) = - 5 \\ \\ or \\ \\ r = - (275)/(55) = - 5`

Since the common ratio is the same for any of the terms chosen , the common ratio is - 5
