Show that the set is infinite by placing it in a one-to-one correspondence with a proper subset of itself. Give the general term of the original set, and show its pairing with its proper subset. (30,33,36,39,42,...)
The general term of the set is
(Type the expression using n.)
Given the first term of the proper subset, type the next 3 terms and the general term. Assume that the numbers will continue to differ by 3.
