Hi,
I have added the calculations below.
c1 c2 Calculation 1 5.5 =((0+10) + 1)/2 =((prev(c2)+10)+c1)/2 2 8.75 =((5.5+10) + 2)/2 3 10.875 =((8.75+10) + 3)/2 4 12.4375 =((10.875+10) + 4)/2 5 13.71875 =((12.4375+10) + 5)/2 6 14.859375 =((13.71875+10) + 6)/2 7 15.9296875 =((14.859375+10) + 7)/2 8 16.96484375 =((15.9296875+10) + 8)/2 c2 column values is the expected result.
