1. Given two sequences in R:
%3|
a. Describe each sequence by giving the type of sequence, nth
term, and sum of the first n terms.
b. Show that the sets containing the elements of (a,) and (b,) are
equinumerous, i.e.,
{2,6, 18, 54, 162, ...} ~ {2,5, 8, 11, 14, ...}.
Hint: Define a function f : {2,6, 18, 54, 162, ...} → {2, 5, 8, 11, 14, ...} then
prove that it is bijective.
