Definition: Blumping is a term used in the context of mathematics, specifically in probability theory. It refers to a sequence or process that exhibits a pattern where each element in the sequence either increases or decreases by an amount equal to its predecessor. This behavior can be described as "blumping" because it resembles the way a rolling stock increases or decreases on a railway line. In mathematical terms, blumping is typically represented by the following formula: P(n) = (1/2)n where P(n
