A sequence is a list of numbers that follows a certain pattern or rule. For example, 2, 4, 6, 8... (even numbers) or 1, 3, 9, 27... (powers of 3).

Patterns help you guess the answers and solve problems faster, which makes math easier. If you know 2n or n², you can save time on multiplication and algebra problems.
