Determine the limit of the sequence or show that the sequence diverges. If it converges, find its limit. an= (-1) + 18 n Step 1 of 4 Recall that if f(x) is a function on (0, ), lim_ f(x) = a and an = f(n) for any positive integer n, then X0 lim an = n - o 1 n + 18 Let bn Write f(x) so that f(n) = b for any positive integer n. f(x) = n X Therefore, f(x) is a function on (0, 0).
