1. The problem statement, all variables and given/known data Given a sequence <xn>n of real numbers. Give the conditions for a real number a not to be a limit point of the sequence. (lim xn not equal to a.) 3. The attempt at a solution I'm really not sure if this is the whole answer or if it's only a part of it: For all e>0 there exists an n that belongs to the real numbers s.t. |xn - a| >= e. Is there more to this or do I have it correct?
