# Which dots-type in math? [duplicate]

This question already has an answer here:

I am using the vim latex suite and when I type ... it automatically changes them into \ldots if it is text or \cdots if I am in a math environment. So I thought that \cdots is the "right" thing to use in math.

But I just now saw that using \cdots it looks very odd with something like this:

$b_{1}, b_{2}, \cdots, b_{n}$


In the document it looks simliar to this formatting: b1,b2,... ,bn After the dots and before the comma there is a whitespace. If I use \dots there is no space at all between them.

What would be the right way to do dots? Should I just stay with \cdots but which lookes a little bit strange? Should I use \cdots and add spaceing by myself where I need it?
