Moving Avg Calculation

[sv12]

Hi,

I am trying to calculate moving Average for the below data:

I greatly appreciate some help in DAX script.

I do not have any Date/Calender table.

Thanks

Running Average Measure = DIVIDE(CALCULATE(
    SUM('Table1'[10 Week]),
    FILTER(
        ALLSELECTED('Table1'[Date]),
        ISONORAFTER('Table1'[Date], MAX('Table1'[Date]), DESC)
    )
),
CALCULATE(
    COUNTA('Table1'[10 Week]),
    FILTER(
        ALLSELECTED('Table1'[Date]),
        ISONORAFTER('Table1'[Date], MAX('Table1'[Date]), DESC)
    )
)
)
