# College Calculus: Level II Sequences

In this tutorial we are going to take a look at Sequences. We are going to be exploring some different ways to find limits of sequences. There are several definitions that lead us up to a “big” theorem that can sometimes be a very powerful way to show that a sequence converges, and also to find its limit. We are going to talk about definitions of following terms: monotonically increasing, monotonically decreasing, monotonic and bounded. Then we are going to talk about that “big” theorem that tells us what happens if the sequence is both bounded and monotonic.

Hi Professor,

Just a bit confused about Example II. The question does not say take the limit as n goes to infinity, how could you just assume that? :):) Really nice video! Thank you very much!

Are most of the problems in the sequences section for an average Calc 2 class going to be taking the limit?

Post by Taylor Wright on April 16, 2014

In Ex1, how could (an-2)(an+1) be less than or equal to zero if an-2<0 and an+1>0 ? When multiplied together couldn't they only produce a negative value, therefore (an-2)(an+1) should only be < 0 ? I don't see how their product could ever equal zero.

Thank you.

How do you know that the sequence is bounded above by 2 and not by 1 ?

Hello,

in example 2, the notation should (for completeness) should be

lim (n-> inf) 3n+5n^2 / 2n^2 +6
