# What is the term for an ordered set/sequence containing natural numbers zero through x inclusive?

Given a natural number x, what is the term (if any) for an ordered set or sequence that includes the range of numbers 0 through x inclusive, i.e. given the natural number 4, the set would be:

    { 0, 1, 2, 3, 4 }


What would this set be called? Is there any terminology that defines such a set?
