Definition
Let $M$ be a metric space.
Let $\sequence {x_n}$ be a sequence in $M$.
Then $\sequence {x_n}$ is a bounded sequence if and only if $\sequence {x_n}$ is bounded in $M$.
That is:
- $\exists K \in \R: \forall n, m \in \N: \map d {x_n, x_m} \le K$
Unbounded
$\sequence {x_n}$ is unbounded if and only if it is not bounded.
