👉 A sequence is a list of numbers or items in which each item is preceded by its predecessor, and followed by its successor. In other words, it is a collection of ordered pairs where each pair contains two elements. For example, consider the following sequence: 1, 2, 3, 4, 5 - The first element is 1. - The second element is 2. - The third element is 3. - The fourth element is 4. -
