Question

Find the common ratio: .25, .75, 2.25, 6.75, 20.25

Answer 1

0.25 = 1/4

0.75 = 3/4

2.25 = 9/4

6.75 = 27/4

20.25 = 81/4

The denominators are 4 the whole time. We have this sequence for the numerators: 1, 3, 9, 27, 81, ....

The common ratio is 3. We multiply each term of the list mentioned above by 3 to get the next term
