--- cards-deck: default_obsidian --- ## monotone $a_{n}a_{n}+1$ decreasing Can be used to define limits. ## Bounds ### bounded above There is a $M$ such that $a_{n}\le M$ for all $n>1$ ### bounded below There is a $m$ such that $a_{n}\ge m$ for all $n>1$ ## monotone and bounded convergent Definition of 'bounded' ::: Bounded from both above and below. ^1653317426701 You have to specify if it's just above or just below. The [[sequences|sequence]] is [[convergence and divergence of series.|convergent]] if it's monotone + bounded in its direction, or if it's generally monotone+bounded.
