# Increasing sequences

(Redirected from Strictly increasing sequences)

Sequences ${\displaystyle \scriptstyle \{a(n)\}_{n=i_{\rm {min}}}^{i_{\rm {max}}}\,}$ for which the terms belong to a totally ordered set (or linearly ordered set) and such that

${\displaystyle a(n+1)\geq a(n),\quad i_{\rm {min}}\leq n

where

${\displaystyle \exists k\,|\,a(k+1)>a(k),\quad i_{\rm {min}}\leq k

## Nonstrictly increasing sequences

Sequences ${\displaystyle \scriptstyle \{a(n)\}_{n=i_{\rm {min}}}^{i_{\rm {max}}}\,}$ for which the terms belong to a totally ordered set (or linearly ordered set) and such that

${\displaystyle a(n+1)\geq a(n),\quad i_{\rm {min}}\leq n
