Answer:
the common ratio is 1/3
Step-by-step explanation:
to get the common ratio of a geometric sequence we would simply divide and consecutive terms, we divide the second term by the first term
45/135 = 1/3
15/45 = 1/3
5/15 = 1/3
we could see, it is proven that the common ratio is 1/3
here is another test that 1/3 is the common ratio
135 * 1/3 = 135/3 = 45
45 * 1/3 = 45/3 = 15
15 * 1/3 = 15/3 = 5
we could see that by multiplying the common ratio by each term we do get the correct next term
