Average last 3 month

Hi all.

I need to calculate the average of 'Total Sale" for the last 3 months.

My measure:

    AVG_Last_3_Month = CALCULATE ([Total Sale],

                                               DATESINPERIOD ('Date'[Date], LASTDATE('Date'[Date]), -3, MONTH))/3

Is there anyway that for the first month it would be devided by 1, the second month devided by 2, then after the third month it would be divided by 3.

Thank you so much.

$ Rolling Avg 3 Months Tran Months = 
//based on number of transaction months
VAR __filterDate = DATESINPERIOD ( 'Date'[Date], MAX ( 'Date'[Date] ), -3, MONTH )   
VAR __numberofMonths = 
    CALCULATE (
        CALCULATE ( COUNTROWS (  VALUES ( 'Date'[Month] )  ), YourTable ),
        __filterDate
    )

RETURN
DIVIDE (
    CALCULATE (
         [Total Sale],
         __filterDate
    ),
    __numberofMonths
)
