Troy created the following pattern using repeated subtraction. What is the next number in the pattern? 12/5,21/10,9/5,3/2,6/5

I have found the difference of -3/10 but I don't know how to show the work.

After 6/5 ( which is equivalent to 12/10) the next term would be 9/10, and the one after that would be 6/10, which could be written as 3/5.

How would you show the work? I figured out the fraction that was subtracted by using an online calculator to divide the problems.

Hmmm...
 
x, x - 3/10, x - 3/10 - 3/10, x - 3/10 - 3/10 - 3/10 ..... etc.
