=AVERAGE(IF(ISERROR(A1:A10)+ISBLANK(A1:A10),"",A1:A10))

entered as an *array* formula. To enter an *array* formula, hold down
<ctrl><shift> while hitting <enter>. Excel will place braces {...} around the
formula.

Note that I also instructed AVERAGE to ignore Blanks to show you how your
specifications could be expanded.

Another way (less pedagogic, though):

=AVERAGE(IF(ISNUMBER(A1:A99),A1:A99))

This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it
correctly, excel will wrap curly brackets {} around your formula. (don't type
them yourself.)
