Assuming the columns are adjacent - by using the Width argument of Offset

This averages last 10 entries of columns A and B
=AVERAGE(OFFSET($A$1, COUNTA($A:$A) - 10, 0, 10, 2))

I am trying to calculate a running average of the last 10 items I place
in
a
row. Is there an easy way to do this?


Rob, Thanks. What if I also want to include another column?
