Let $\{ a_j \}_{j \in \mathbb{N}}$ be any sequence of real numbers satisfying the following property:
There exists a number $N \in \mathbb{N}$ such that $a_k<a_j$ for all $k\geq j+N$.
What is such a sequence called?
If $N=1$, $\{a_j\}_{j \in \mathbb{N}}$ is of course an decreasing sequence.
One example of such a sequence with N=2 is -1,0,-2,-1,-3,-2,-4,-3,...
