Answer:
The answer is - 5
Step-by-step explanation:
To find the common ratio of a given sequence , divide the previous term by the next term
We have
[tex]r = - \frac{55}{11} = - 5 \\ \\ or \\ \\ r = - \frac{275}{55} = - 5[/tex]
Since the common ratio is the same for any of the terms chosen , the common ratio is - 5
