You can copy this formula into cell H2 and copy down...

=AVERAGE(INDIRECT("E" & MAX(2, ROW()-H$1+1) & ":E" & ROW()))

INDIRECT - returns a Range given a string address.
ROW - Returns the Row of the current cell, so the formula in cell H7 will return 7

The part "MAX(2, ROW()-H$1+1)" returns the row X cells up (where X = H1), to the maximum of 2. I did this so it wouldn't return an error for row < the value in cell H1. If you want those cells blank instead, use this in cell H2 and copy down.

    =IF(ROW()<=H$1, "", AVERAGE(INDIRECT("E" & ROW()-H$1+1 & ":E" & ROW())))

This will return blank if the row is less than the value in cell H1.
