In a code the $$n^{th}$$ letter in the English alphabet is coded as the $$r^{th}$$ letter of it, where r is the remainder when 3n + 2 is divided by 26. For example, the $$7^{th}$$ letter G is coded as W since 3.7 + 2 = 23 and W is the $$23^{rd}$$ letter; the $$8^{th}$$ letter H is coded as Z since 3.8 + 2 = 26 and Z is the $$26^{th}$$ letter in the alphabet. The reverse is used for decoding. Based on this coding and decoding answer Questions.
