A limit of a sequence is definetely convergent if:(adsbygoogle = window.adsbygoogle || []).push({});

If for any value of K there is an N sufficiently large that an > K for n > N, OR for any value of K there is an N sufficiently large that an<±K for n > N

My only question is what exactly are K, N, an and n? What values are they? How would they be graphed? I.e. for the sequence a(n) = 2n

n = 2

an = 4

What are K and N? Are they on the horizontal or vertical axis?
