Question

Find the common ratio of the geometric sequence 17,-51,153,...

Answer 1

Answer:

The answer is - 3

Step-by-step explanation:

To find the common ratio ( r) of a given sequence , divide the previous term by the next term.

That's

$r = - \frac{51}{17} = - 3 \: \: \\ or \\ r = - \frac{153}{51} = - 3$

Since the common ratio is the same for any of the terms chosen , the common ratio is - 3
