The first rule is multiply by 2, then subtract 4 starting from 6. The second rule is add 3, then multiply by 2 starting from 1. What are the first four ordered pairs using the two sequences? (0, 0) (6, 1), (8, 2), (12, 22)
(6, 1), (10, 8), (14,22), (22, 50)
(6, 1), (8, 8), (12, 20), (20, 45)
(6, 1), (8, 8), (12, 22), (20, 50)

(6,1), (8,8), (12,22), (20,50)
