Averaging across sequences of cells?

Hello,

I want to take averages of every few cells. For example, I might want to take the average of a1, b1, c1, then have the next cell take the average of d1, e1, f1, then the next take g1, h1, i1. However, when I use the average function, for example =average(a1, b1, c1), and drag the cell, the next cell will take the averages of b1, c1, d1 instead of c1, d1, e1.

Is there a solution to this?

PS: I am actually taking a much more complicated cell range average, but I do not think that is the problem; the problem is with how the cells are moved when the formula is dragged. However, if it might make a difference, the actual formula I am using is:
=AVERAGE(INDEX(Data!B24:$LGW24, ROWS(B5:B5)-1 + COLUMNS(B5:B5)), INDEX(Data!B24:$LGW24, ROWS(B5:B5)*7+COLUMNS(B5:B5)), INDEX(Data!B24:$LGW24, ROWS(B5:B5)*14+COLUMNS(B5:B5)))

How to calculate loan payments in Excel?
Use the PMT function: =PMT(5%/12,60,-25000) is for a $25,000 loan, 5% annual interest, 60 month loan.
Something to test...

Type: =AVERAGE(A1:C1) into cell C2
Type: =AVERAGE(D1:F1) into cell F2

Then select A1:F1 and autofill the selection across row 2. This will average each set of three cells as specified in your OP.

well, I can't do that because of how the data is structured in the table: I don't have the blank space within the table to do it given how much data there are. But I did find a solution: multiply the index rows by the number of offsets, found by dividing the index of the column by the number of cells to be averaged.

Thanks for your advice!

=AVERAGE(INDEX($A$1:$L$1,0,(ROWS(A$3:A3)-1)*3+1):INDEX($A$1:$L$1,0,
     (ROWS(A$3:A3))*3))
