Hi, and thanks.

This formula works fine: =AVERAGEIF(A:A,""&MAX(A:A)-14,B:B)

This formula I could not get to work:
=AVERAGE(OFFSET(B22,-13,0,14,1))

Thanks for the quick responses.

Glad to help. Thanks for the feedback.

I did not test Jim's formula, but I suspect it is not working because your data is not set up exactly as he described.
