Sequential (consecutive) refers to a series of events or items that follow one after another in a specific order. This concept is often used in various fields, such as mathematics, programming, and storytelling, where the arrangement of elements is crucial for understanding or functionality. For example, in a story, the plot typically unfolds sequentially, with each event leading to the next. In mathematics, sequential numbers are those that follow a specific pattern, like 1, 2, 3, 4, where each number is one more than the previous one. In programming, sequential execution means that commands are processed in the order they are written, ensuring that each step is completed before moving on to the next.
