Hello,
Martindwilson provided this formula on a different thread:
=AVERAGE(OFFSET(P3,,MATCH(1E+100,P3:AAD3)-A1,1,A1))
It almost works for me but I need it to ignore cells that are empty.
Can some one help me out please?
Many Thanks
C.

Hi Cryptic,
welcome to the forum.
And those n number range is including blanks for example - last 20 numbers to be averaged in a range of A1:A100 so will your consider A80:A100 or A75:A100 if 5 are blank cells in both the cases ?

In a range of A1 to A100 where there are 5 blank cells I need the average of the last 20 numbers.
So, if A81 and A82 are blank the range to be averaged would be A78 to A100 with the total still being divided by 20 and not 22.

See the attached file where I have used a defined name "data" having logic as:-

It will always count last 20 values - ignoring blanks. You can change 20 to your choice OR reference that from a cell.

You could try this CSE array Confirm with Ctrl+Shift+Enter not just Enter

To avoid the CSE entry you can use a defined name

Run out of time to look at this properly tonight and the server is really slow.
I will try again tomorrow.
Thanks again
Hello again,
I have tried unsuccessfully to modify some of your suggestions to work on my spread sheet.
I have attached a sample (which is, of course, what I should have done in the first place).
I need to find the average of the last n numbers(A1)in each row while ignoring the blank cells.
Thanks for helping again.
I'm getting really peed off with this site crashing.
See if this workbook does as you need.
Column AI averages the last n elements if there are at least n elements in the row, if not "" is returned.
Column AK averages the last n elements if there are less than n elements the whole row is averaged.
Thanks very much Marcol,
This is exactly what I needed. I don't fully understand how it works but you have made me look a like genius!
Thanks again
C
Happy to have helped.
Be careful, they will just load more work on you ...
