Question: 1. For each of the following closed forms, write out the first several terms of the sequence (at least five) and use this to create a recursion for the sequence.
(a) an = 5n - 2,
(b) an = 3n + 1,
(c) an = 7n - 6,
2. Check out the graph G shown in Figure:
(a) Draw G\v4 (a.k.a. G-v4).
(b) Now draw G\e (a.k.a. G-e).
