Percentage of row amount over previous row

[Aquila]

Hello, I have the following table ,

, my question is to know how I can get by DAX, the percentage of a row with respect to the previous one, which is what is colored in red. The idea is to develop a measure (not a calculated column).
Regards.

Hi:

May be something like this?

Step 1:
Add index column


Step 2:

Calculate Previous sales as Measure


Step 3:
Calculate Percentage difference as column


Thanks
