notation - two or three dots

I have a more general question to ask:
about using the symbol.



As far as I have heard three dots will represent that it continues up to infinity.



And I have found (mostly in computer programming) that two dots will be used in a case to indicate the terms between two specific points.




So my question is what is suitable to write in a case where finite number of terms are used.



For example Consider the set with n number of elements. Let them be
x1,x2,xn two dots.  Or is it x1,x2,xn?
