Autopopulate a column

[medico]

I have a column with certain values and corresponding values in the next column. I want to be able to autopopulate a 4th column with the 3rd column equispaced, as shown in this figure. I only put 17 rows to get the message across, but I would eventually have until 36 in column "cr3." could you please help? Thanks

cr1	cr2	cr3	populate
0	1	0	?
1	17	1	?
2	17	2	?
3	4	3
4	9	4
5	8	5
6	7	6
7	2	7
8	1	8
10	3	9
11	1	10
13	1	11
14	1	12
16	1	13
18	1	14
36	1	15

Not really understanding your question.

Your figure is a bit unclear.

Also not familiar with the term "equispaced".

Do you want the 4th col to = ?, if so key "?".

If the 4th col is to equal the 3rd col, use for example "=C2" in D2 and drag the formula down the number of required cells.

Maybe this will give you a start or will allow you to re-word your question so that I or others may be able to assist.
