Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers(Generally, the scope of high school math defines this subset as the set of natural numbers 1, 2, 3, 4, ) By graphing or calculating terms, students should be able to show how the recursive sequence a1 = 7, an = an 1 + 2; the sequence sn = 2(n 1) + 7; and the function f(x) = 2x + 5 (when x is a natural number) all define the same sequence.
