QUES TION: You're playing a game with
a friend. She names any positive integer she likes, and you win if you can
find that many consecutive composite
(i.e., non-prime) numbers. If she says
"three," you can win by saying " 8, 9,
and 10," for example. Can you find a
strategy to win this game 100% of the
time? —Derek Bronish
