Hey guys, I've been into brainteasers since I was little and recently decided to make a puzzle-related website. I figured that this will be the best place to share some of my problems and see if they are any fun. I guess they are too easy, but hope that will entertain you for a bit.
Just another sequence
1, 3, 7, 12, 18, 26, 35, 45, 56, ?
P.S. Please, let me know if you have seen identical puzzle elsewhere, don't want to take someone's credit, even accidentally.
