Understanding Sequences: Boundedness, Monotonicity, and Convergence

The video tutorial explains how to analyze a sequence given by a formula. It covers the simplification of the sequence, checks if it is bounded, and determines if it is monotonic. The tutorial also discusses whether the sequence converges or diverges, and if it converges, the value it converges to. The sequence is shown to be bounded, monotonic, and convergent, with a limit of zero.

What is the simplified form of the sequence a_n = n^4 / n^6?

• 1 / n^2

• n^2

• 1 / n^4

• n^6

What does it mean for a sequence to be bounded?
