Averaging a total in excel with a slight problem?

I know that by using "=average()" I can have a cell for each day of the month and as I enter a value in each cell it will average the total of cells day to day. The problem I have is one cell contains 3 days worth of data.

Ex. A1- 50

A2- 50

A3- 50

A4- 125 (50+50+25)

A5- 50

The average calculates it as 50+50+50+125+50/5= 65. I need it to count the one cell as 3 entries as in 50+50+50+125+50/7=46.4. I can not enter the data in any other cell but still need to calculate like it was. Thanks ahead of time if you can figure it out.

Update:

It just adds 2. As in instead of 65 it gives me 67. Any other ideas...

    that A4 cell was a bad idea

    so if =AVERAGE(A1:A5) gives you the wrong 65

    then an Average is simply a SUM 325 divided by a COUNT in this case 7...but if you look at it, the count is 5....so you need to add 2

    this should work with a copy&paste

    =SUM(A1:A5)/(COUNT(A1:A5)+2)

    let me know how it works.

    expletive_xom is correct. Did you enter it exactly as written? Parentheses in the right place?

    =SUM(A1:A5)/(COUNT(A1:A5)+2)
