Advertisements I have a sequence, and I am trying to make a program to find the nth term of the sequence. The sequence is as follows: 1, 11, 21, 1211, 111221, 312211… In this sequence, each term describes the previous term. For example, "1211" means that the previous term; the previous term is "21" where… Read More Finding the nth term in a sequence
