Each Friday morning I post a riddle to get you to think outside the box and exercise your brain. If you are stumped, share it with a friend or colleague and see if you can figure out the answer together.
Leave your answer in the comment section. I’ll approve responses later in the day to give people a chance to respond without seeing any spoilers.
This week’s brain teaser:
9 = 72
8 = 56
7 = 42
5 = 20
3 = ?
I previously shared this but decided to re-post since it was so popular.
Good luck!

Each number is multiplied by 1 less then itself. The formula is y(y-1).
