Assuming that Demand Quantity is a measure, you could try

Avg 8 weeks =
VAR currentEndWeek =
    LOOKUPVALUE ( 'Date'[End of week], 'Date'[Date], TODAY () )
VAR finalEndWeek = currentEndWeek + 56
RETURN
    AVERAGEX (
        ADDCOLUMNS (
            CALCULATETABLE (
                VALUES ( 'Date'[End of week] ),
                'Date'[End of week] >= currentEndWeek
                    && 'Date'[End of week] <= finalEndWeek
            ),
            "@val", [Demand Quantity]
        ),
        [@val]
    )

Hi  @Srikantht ,

I created some data:

Here are the steps you can follow：

Create measure.

Measure =
var _today=TODAY()
var _week=WEEKNUM(_today,1)
return
AVERAGEX(FILTER(ALL('Table'),'Table'[week]>=_week-8&&'Table'[week]<_week),[rand])
