|a_n - a| < \varepsilon</math> for every <math>n > N</math>. Intuitively, this means that if you have an infinitely small ball [[center]]ed at the limit point, then most of the points of the sequence are in that ball.

|a_n - a| < \varepsilon</math> for every <math>n > N</math>. Intuitively, this means that if you take  an [[interval]] as small as you like, [[center]]ed at the limit point, then most - i.e., all but a finite number - of the points of the sequence are in that interval.
