RIDDLE: COUNTING TO 50
Henry and Gretchen are going to play a game. Henry explains, "You and I will take turns saying numbers. The first person will say a number between 1 and 10. Then the other person will say a number that is at least 1 higher than that number, and at most 10 higher. We will keep going back and forth in this way until one of us says the number 50. That person wins. I'll start."
"Not so fast!" says Gretchen. "I want to win, so I will start."
What number should Gretchen say to start?
ANSWER: She wants to say "6". The series of numbers she will say is 6, 17, 28, 39, 50. Since she wants to say 50, she needs Henry to say a number between 29 & 38. So she wants to say 28. Following this same logic recursively, she will want to say 17, and she will want to say 6 to start the game, and be assured victory.
