What are limit points of a set?
So, if I have a set and I keep on finding points that get arbitrarily close to some point outside the set, then that outside point is a limit point?
That's correct! If a set has a limit point then it is said to be dense. A sequence can be used to find a limit point in a way that is analogous to finding the limit of a function as x approaches a given value.
