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 origina subset. {12, 16,20,24,28,..} 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 4. Original set {12, 16, 20, 24, ., 4n + 8} Proper Subset {16 (Type the general term using n.)
