Try

=MIN(IF((ISNUMBER(A1:A300))*(ROW(A1:A300)),ROW(A1:A300)))

=MAX(IF((ISNUMBER(A1:A300))*(ROW(A1:A300)),ROW(A1:A300)))


...BOTH confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer.

Or:

=MATCH(TRUE,INDEX(ISNUMBER(A1:A277),0),0)

=LOOKUP(10^37,A1:A277,ROW(A1:A277))
