A number series is a sequence of numbers arranged in a specific order, often following a particular pattern or rule. These patterns can involve simple arithmetic operations, such as addition or subtraction, or more complex functions. Number series are commonly used in mathematics to help identify relationships between numbers and to solve problems. In various fields, including mathematics, computer science, and puzzles, number series play a crucial role. They can be used to test logical reasoning and analytical skills. Recognizing the underlying pattern in a number series can lead to predicting future numbers or completing missing elements in the sequence.
