First divide the 2nd term 150 by the 1st term 100 to get
150%2F100=1.5

Now divide the 3rd term 225 by the 2nd term 150 to get
225%2F150=1.5

Now divide the 4th term 337.5 by the 3rd term 225 to get
337.5%2F225=1.5

Now divide the 5th term 506.25 by the 4th term 337.5 to get
506.25%2F337.5=1.5

So if we pick any term and divide it by the previous term, we'll always get 1.5.


So the common ratio is 1.5
