I was visiting my cousin, a mystery writer and lover of puzzles, when I noticed this list of numbers on her white board.
"Is this part of a new puzzle you've been working on?" I asked.
She responded, "Well, I don't know if I'm going to use it yet, but yes. The answer would be the next number in the list."
Never able to solve her puzzles, I just asked what the next number was.
To my surprise, she replied, "I haven't figured that out yet."
But when I asked her more about, she chuckled and wouldn't tell me anymore. She just said it was easy enough and I'd figure it out eventually. It's been a long time and I haven't figured it out.
What number comes next?
