My list, see example below may have a number in each row or it may not. I
trying to write a formula that would average the numbers no matter how many
there were. Example if there were 4 cells filled each with a number, the
formula would divide the sum by 4. if there were 5, the formula would
recognize there are 5 and would divide the sum by 5 and so on. Thanks

????? This is the average ( which would be 51.68 in this case )of how ever
many actual numbers are in the list from 0 to 10 numbers possible. What
would be the formula?
