Multi-row formula tool example

Question

I am currently in a college course that uses Alteryx. We are learning how to use the Multi-row formula. I was having some difficulty understanding the concepts on how to use the expressions ,so I went to the examples by Alteryx. In the example on how to "Access Additional Rows and Change Values for Rows that don't Exist" which calculates a 3-month rolling average, I don't understand how they came up with the value for column 3 Month Average, record 2. The value is 326.00 ,but this is not the average of the row 1 and 2 sales.

Hi @meghussong

The formula references the current, and previous two rows. As you set for values where rows doesn't exist to the closest valid row, it takes the average from record 1 twice and record 2

@meghussong 
se what actually happened here is when it was unable to find the previous rows it was taking values from first row
for first row -290+290+290/3 = 290
for second row - 398+290+290 /3 = 326

rest youl know how values are achieved.
