The video tutorial explains how to find the limit of a sequence using a theorem that relates sequence limits to function limits at infinity. It covers two methods: dividing each term by the highest power in the denominator and using a shortcut based on comparing the degrees of the numerator and denominator. The tutorial concludes with a graphical representation of the sequence's convergence to zero.

What is the main goal when finding the limit of a sequence?

• To determine if the sequence is increasing

• To find the sum of the sequence

• To find the value the sequence approaches as n becomes very large

• To check if the sequence is periodic

According to the theorem, if the limit of f(x) as x approaches infinity is L, what can be said about the sequence a_n?

• a_n is undefined

• a_n converges to L

• a_n diverges

• a_n oscillates

What is the first step in finding the limit at infinity for rational functions?

• They remain constant

• They oscillate

• They approach zero

• They become infinite
