Definition:Upper Bound of Sequence

Definition
A special case of an upper bound of a mapping is an upper bound of a sequence, where the domain of the mapping is $\N$.

Let $\left({T, \preceq}\right)$ be a poset.

Let $\left \langle {x_n} \right \rangle$ be a sequence in $T$.

Let $\left \langle {x_n} \right \rangle$ be bounded above in $T$ by $H \in T$.

Then $H$ is an upper bound of $\left \langle {x_n} \right \rangle$.
