Edit 3: Seeing that no one has answered for a bit of time, here's a new hint! The number is between 56—100!
Answer: 78 (a number between 56-100)
I've had my own theory on how to get the right number, and deducing it with the word
between is one way to put it. Unfortunately, I would've answered with a luck-based guess, but I know that wouldn't be the right answer because it is illogical and distinctly intuitive. However, since you used an en dash, I found myself wrong... though, I know it wasn't that easy.
In any case, there are 144 (56-200) and 44 (56-100) combinations to find the right answer, and well, if some would find it, then I clap my hands to you.
