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.)
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?
