I do not talk about "every given n" but about "every n" (this means from 1 to n for every n). Note that "there is a last n" but it is not a findable natural number.
Note that you do not need the x_n to exist to say something about them. For example, you can say no x_n that will ever exist will be equal to 0. If you say x is coFIS to y you are saying something about x_n and y_n that may not exist at this time.
