What is the common ratio r in the geometric sequence .5, 1.5, 4.5, 13.5, 40.5,… ? This is one of the questions form my homework my friend told me he got 3  but I don't understand how he go 3.

The common ratio of the sequence would be:

40.5 / 13.5 = 3

 13.5 / 4.5 = 3

4.5 / 1.5 = 3

1.5 / .5 = 3

Every term would be divided by the preceding term in order to find the common ratio.

All of the ratios equal 3 this indicates that 3 is the common ratio.
