I am trying to take an average of a changing range of numbers.
The range always starts at A2 but ends at different rows of column A.
If I'm using the formula =AVERAGE(SMALL(A2:A??,{1,2,3,4,5})), how do I
determine A?? (the last row containing data).
Note: I have a field that contains the next available row number, so I could
use it minus 1 except I don't know how to get the formula to use this value.

Thanks for any help.
