Problem of the Week
Tuesday, April 16, 2018
Max announces that he is writing down two consecutive counting numbers {1,2,3,4.....} on two separate pieces of paper. He hands one of them to Kevin and the other to Michael. Michael looks at his and says to Kevin, "I don't know your number." Kevin says to Michael after looking at his number, "I don't know your number either." Michael then jumps up declaring. "Now, I know your number!!" What is Michael's number? What is Kevin's number?
