Perhaps something like:

=AVERAGE(LARGE(A1:A10,ROW(1:4)))

entered as an array formula with <Ctrl <Shift <Enter. This will give you
the average of the 4 largest numbers in the range A1:A10.

=AVERAGE(LARGE(A1:A10,{1,2,3}))

Using the array constant allows the above formula to equate as a regular
formula!

Hi!

A non array entered version:

=AVERAGE(LARGE(A1:A100,{1,2,3,4}))

Of course, if you wanted the largest 50 you wouldn't want to use the above
method!

Another method:

=SUMIF(A1:A100,"="&LARGE(A1:A100,4))/4

That fails when the 4th largest value appears multiple times.

True
