Well, I finally figured out #2. Basically each series is a set of 3 numbers. The first 2 numbers of the 3 numbers is multiplied by an incrementing number. (1 x 3 = 3, 3 x 3 = 9) and then (2 x 4 = 8, 8 x 4 = 32) The next number if the sequence would then be: (3 x 5 =15, 15 x 5 = 75).

I'm still stumped on #1 though.
