Definition:Strictly Decreasing/Sequence

Definition
Let $\struct {S, \preceq}$ be a totally ordered set.

Then a sequence $\sequence {a_k}_{k \mathop \in A}$ of terms of $S$ is strictly decreasing iff:


 * $\forall j, k \in A: j < k \implies a_k \prec a_j$

Real Sequence
The above definition for sequences is usually applied to real number sequences:
