Anything that's not a multiple of any factor of ten. So it could have been 1, 3, 7, 9, 11, 13...
Edit: well, okay, not 1, since you specifed that in the problem.

The integer cannot be an even number, because there are an even number of dots, so you will eventually land on a dot that is already colored. The integer also cannot be a factor or a multiple of 10, because you will run into the same problem. Integers less than 10 that will work for this problem are 3 and 7.

Well you didn't give us any choices, but it could be anything other than 2 or 5. If it is one of these then Kim would repeat.
