Calculatng bowling averages

[Michael]

Howdy,
Cells a1, a2, a3 contain bowling scores.
Cell a4 is the total of a1:a3
Cell a5 is the total in a4 divided by 3 (total games bowled so far) equaling the bowler's average
that week.

Cells b1, b2, b3 contain the next week's bowling scores.
Cell b4 is the total of b1:b3

NOW, in cell b5, I want the the total pins felled from cell a4 PLUS the total pins felled in cell b4
divided by 6 (total games bowled so far).

I know how to set THIS up, what I don't know is how to extend this formula easily for the next 28
weeks! When I drag the formula, it no longer starts with the data in a4. It jumps ahead by one
column each week. I have to manually change the range of cells I want to add together then change
the number that is divided into that range.

Here is a sample starting in cell a4. I entered this manually. It's the formula in row 5 that is
giving me the fits. How can this be done with dragging the cells or entering a different formula?

Thanks....(I'm outta breath now....)

=SUM(A1:A3) =SUM(B1:B3) =SUM(C1:C3) =SUM(D13) =SUM(E1:E3)
=SUM(A4)/3 =SUM(A4:B4)/6 =SUM(A4:C4)/9 =SUM(A44)/12 =SUM(A4:E4)/15

Hi!

Try this in cell A5:

=IF(A1="","",ROUND(SUM($A$1:A3)/COUNT($A$1:A3),0))

Copy across as needed.

The formula will return blank until an entry is made in
the cells in row 1.

This is also more flexible than using a hardcoded divisor
that you would need to change if someone didn't bowl all 3
games.

=SUM(A4)/3 =SUM(A4:B4)/6 =SUM(A4:C4)/9 =SUM(A44)/12 =SUM(A4:E4)/15

Well, another approach:

In A5 enter the formula

=AVERAGE($A$1:C1)

and drag it down as far as needed.

If you want to suppress output if there are no games in the row, then use:

=IF(COUNT(A1:C1)<>3,"",AVERAGE($A$1:C1))

Well I sure do appreciate the responses! My old brain would have never even thought of formulas
like these!

Very much appreciated!

That is one super-duper formula! It worked and I appreciate your time!
You just made bowling more fun as well as Excel!
