1. Double the previous term

2. Triple the previous term

3. +2, +3, +4, +5, +7...

4. +3, +5, +7, +9, +11... OR square each number, they're the same thing

5. f(n) = n3

6. f(n) = f(n-1) + f(n-2)... Think that's right.

Nice one. I must have been the one who was tired. I totally missed your hint at the bottom.
