measure for week over week changes

[gkim]

I'm trying to figure out how to make a measure for the week over week changes.

I have these columns below in my data:

Year: 2018 and 2019

Week number: 1,2,3,4.....for each year

Account Name&Number

Volume

Revenue

I need to calculate Week over Week Volume and Revenue absolute changes and %.

For example, 

2019 week 3 volume: 2000

2019 week 4 volume: 3000

Need a measure for the difference between these weeks

+1,000 and +50%

could you please help?
