View Full Version : Limits of a sequence

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

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

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

Thanks.

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?
