How to find avg for specific step size? I have annual data and want to find
weekly avg. i.e avg A1:A6 then A7:A14 etc.. How to do it using sigle formula?

One way ..

Source data is assumed in A1 down

Put in any starting cell, say in B2:
=AVERAGE(OFFSET(INDIRECT("A"&ROW(A1)*7-6),,,6))
Copy B2 down

B2 returns: =AVERAGE(A1:A6)
B3 returns: =AVERAGE(A7:A14)
and so on ..
