Question Mark's Function MachineMath brain teasers require computations to solve.
Question Mark is very proud with himself. He has just designed his very own function machine. When a number goes into this machine, a different number comes out. A basic formula is used to determine what comes out. If:
3 -> 90 4 -> 272 5 -> 650 6 -> 1332 7 -> 2450 What will come out if 10 goes in? 
What Next?
