👉 In the context of mathematics, "merls" is a term used to denote a sequence or function that alternates between positive and negative values. Specifically, it refers to a sequence or a function where each element in the sequence either increases (positive) or decreases (negative), starting from 0. For instance, if we define the sequence as follows: 1. \(x_1 = 0\) 2. \(x_{n+1} = -x_n + n\)
