What result do you want if all the cells contain numbers?

This shouldn't be too diffacult but I can't seem to find the function that
would allow me to sum the cells with numbers and then divide that by the
number of blank cells.
e.g. cells A1:A5, if A1 is 5, A2 is 10 and cells A3 through A5 are blank
then the answer would be 5. 5+10/3=5
I tried isnumber and isblank but that doesn't work. Any ideas?
