👉 In mathematics and computer science, a "prevue" is a sequence of numbers or elements that are either strictly increasing or strictly decreasing. This concept arises from the notion of monotonicity in analysis, where a function f(x) is said to be strictly monotone if it increases or decreases at each point on its domain. A sequence of numbers \(a_1, a_2, \ldots\) is called a "prevue" if for every positive integer k, the values of
