Ok, so I found this formula online, and have adjusted it to fit my needs and it works generally.
=AVERAGE(INDEX(L6:FZ6,LARGE(IF(L6:FZ6<>"",COLUMN(L6:FZ6)-COLUMN(L6)+1),3)):FZ6)
However, the formula calculates the average of the LAST 3 non-blank columns. I would like the formula to calculate the average of the FIRST 3 non-blank columns starting with column L. Any ideas?
Thank you all in advance.
