How to sum the last 7 number in a row?
 

This probably has an easy solution but I just cant figure it out. I have
search this discussion board but cant find anything.
Anyways I was wondering if there is a formula that sums the last 7 entries I
entered in the row.

An example would be.
D5 E5 F5 G5 H5 I5 J5 K5 L5 M5 N5 O5
2 5 1 3 5 1 0 2 4 2
D5 is where I want the sum of the last 7 numbers. and everyday I would add a
number at the back and do not want to change the range everytime I do so. is
there a way to make D5 return the last 7 numbers I have entered in the row
and will readjust everytime I add another number?

How to sum the last 7 number in a row?
 

Will there always be at least 7 numbers to sum? What should happen if there
isn't at least 7 numbers to sum?

Have a help cell - perhaps D3
=COUNT(E5:IV5)

and in cell D5
=SUM(INDIRECT("R5C"&MAX(5,D3-2)&":R5C"&D3+5,FALSE))

You may need to play with this one to make sure you know what it is doing....

So long as there are at least 7 numbers, and they start in E5 and run
consecutively, then:

D5: =SUM(OFFSET(D5,0,COUNT(E5:IV5),1,-7))

might do it.

Try this:

=SUM(OFFSET(E5,,COUNT(E5:IV5)-1,,-7))
