Hello all, indeed this is always a question in my mind.

For a sequence, we can study the limit, let's say [tex]\lim_{n\rightarrow\infty} x_{n} = c[/tex] where [tex]c[/tex] can be [tex]\infty[/tex].

So whenever we talk about this kind of limit, we are generally interested in a sequence which would not attain [tex]c[/tex] at a finite value of [tex]n[/tex]. In other words, the sequence in the form of [tex]x_{n} = c[/tex] where [tex]n \geq N[/tex] for some finite [tex]N[/tex] is of no interest because the limit is trivial?

Thanks.


Wayne

If it becomes constant, then it's a pretty boring sequence, but unless you have some reason to believe so you shouldn't assume that the sequence can't be of that form. Do you have a specific context from which this question is coming?
