One way...

Assume data starts in cell A2. Enter this formula in B2 and copy down:

=IF(MOD(ROWS(B$2:B2),5),"",AVERAGE(OFFSET(A2,,,-5)))

In D5 enter the below formula and copy down as required
=IF(MOD(ROW(),5),"",AVERAGE(A1:A5))

If this post helps click Yes

 

[Teethless mama]

In D1: =IF(MOD(ROW(),5)=0,AVERAGE(OFFSET(A1,,,-5,)),"")

copy down as far as needed
