"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Assuming you wanted to start at row 1, then this would work.  I'm sure there are many other ways to accomplish this also.

=TRUNC((ROW()-1)/3)+1

Many thanks, but how do I start at a particular number instead of 1?
Cost AccountantCommented:
You can also use INT:

=INT((ROW()-1)/3)+1

Change the +1 at the end to start from a diferent number (in both formulas)

Just change the "1" at the end of the formula.

Assuming you are entering the first number in the first row required, use this formula in rows below it:

=IF(COUNTIF(M\$1:M1,M1)>=3,M1+1,M1)

This assumes starting at M1 but can start on any row with manual entry in first cell. Adjust the number in bold for the number of rows required.

Thanks

Although the question is closed, I would have used this approach:

Enter the three ones in A1, A2, A3.
In A4 enter the formula =A1+1
And copy this formula down.
Excel & VBA ExpertCommented:
More robust approach would be like this....

=INT((ROWS(A\$1:A1)-1)/3)+1

This way you can place your formula in any desired cell and copy it down.
