Average of 6 cells on too long file

[canada123]

Hi,

Attached spreadsheet is the example. I need to calculate and show average of each 6 cells in a column. The file is too big so please avoid copy/paste function.

I will appreciate your time and help.

Thanks in advance.

Hi Canada,

Looks like an Indirect formula using Rows... Something like:
=AVERAGE(INDIRECT("A"&INT((ROW()-2)/6)+2 &":A"&INT((ROW()-2)/6)+8))

See the attached.

=AVERAGE(INDEX(A:A,CEILING(ROW(A1),6)-4):INDEX(A:A,CEILING(ROW(A1),6)+1))

In C2
=AVERAGE(INDEX($A$2:$A$19,(INT((ROW(A1)-1)/6))*6+1):INDEX($A$2:$A$19,(INT((ROW(A1)-1)/6))*6+6))

Copy down
