What does sequence mean in maths?

In mathematics, a sequence is an ordered list of numbers, known as terms, that follow a specific rule or pattern. Each term in the sequence is typically defined by its position or index, often denoted by ( n ). Sequences can be finite or infinite and can be arithmetic (with a constant difference between terms) or geometric (with a constant ratio between terms), among other types. They are fundamental in various areas of mathematics, including calculus and number theory.
