The sequence "0, 1, 2, ..., n-1" represents a list of integers starting from zero and ending at one less than a specified number, n. This sequence is commonly used in programming and mathematics, particularly in indexing arrays or lists, where counting typically begins at zero. In this context, n indicates the total number of elements in the sequence. For example, if n is 5, the sequence would be "0, 1, 2, 3, 4." This notation is essential for understanding concepts like loops and iterations in computer science, where operations are performed on each element of the sequence.
