1. The first term of a sequence is 13. Starting with the second term, each term is the sum of the cubes of the digits in the previous term. For example, the second term is 1^3 + 3^3 = 28. Find the 100th term.
2. The sum of the first n terms of a certain sequence is n(n + 1)(n + 2). Find the tenth term of the sequence.
Thanks in advance :)
