$x_1$,~$x_2$, \dots,~$x_n$

is OK.

This is how Knuth use in TeXbook.

For me, I would replace the tildes with spaces.

I don't think one should use ... instead of \dots or \ldots.

	it looks like in a normal sentence, `...` should be used instead of `\dots` (at least in French as far as I know). When maths are involved, I am not sure – pluton May 22 '11 at 4:28
	I know nothing about French typography. In modern fonts, there is a `…` symbol and I think it should be used. (It is used when you use `xunicode` with XeLaTeX.) At least in TeX, `\dots,` and `\dots.` are widely used. – Leo Liu May 22 '11 at 4:31
