so if i write
1, 2, ... , n
this means infinite numbers between 1 and n ?

No, not quite. That's not what I implied.
If you establish a pattern (as you did when you said '1, 2'), then the ellipse implies that this continues on forever, unless you specify an endpoint (as you did when you said ', n').
So 1, 2, ..., n means all positive integers up to and including n. What you said ("infinite numbers between 1 and n") doesn't agree with the pattern you established. You're clearly dealing with integers, and there are not infinite integers between 1 and n, no matter what n is (of course assuming n is a real number, but that doesn't really matter anyway).
There's a big difference between "1, 2, ..., n" and 0.000...1. The most important difference is that the former indicates a set, while the latter is a number.
