Sequence and Series

A sequence is an ordered list of numbers, where each number follows a specific pattern or rule, like counting or doubling. For example, 2, 4, 6, 8 is a sequence where each number increases by 2. A series is the sum of the terms in a sequence; for instance, adding 2 + 4 + 6 + 8. Think of a series as combining the numbers in a sequence to find a total. Both concepts help us understand patterns and totals in mathematics, with sequences focusing on the order of individual items and series on their cumulative sum.
