Some Challenging Maths Questions

Over the weekend, I was almost driven to crazy by some mathematics questions. Perhaps you may want to crack your brain to try out:

1) Mary is thinking of a number between 300 and 400. When she divides it by 6 or 8, it leaves a reminder of 5. What number is she thinking of?

2) What are the next three numbers for the following:
a) 1, 3, 5, 15, 17, __, __, __
b) 1, 1, 2, 3, 5, 8, __, __, __

I really appreciate some help on the above questions and thanking you in advance.
