(a) Illustrate a onetoone correspondence between the following sets:
N = {1, 2, 3, 4,. . . , n,. . .}
F = {4, 9, 14, 19, 24,. . .}
(b) In your correspondence, what element of F corresponds to 57? Explain why.
(c) In your correspondence, what element of F corresponds to n?

I see a mapping
such that n > 5n  1
How is that for a hint?
