1, 2, 4, 8, 15, 30, 50, 100, ?

Sir, you never told me what number came next, hopefully you can share the secret.

I also want to take this opportunity to thank you for everything you've taught us these past two years. Due to the high intensity of our classess I know feel more prepared than ever for college and I know that I won't have any problems with calculus. Good luck on your next job,
