Jason said: "Pick any three dates that are next to each other in a week on the calendar. Give me only the sum and I'll tell you your dates."
Noriko secretly chose 14, 15, and 16, and gave the sum 45 to Jason. In a couple of seconds Jason said, "The dates are 14, 15, and 16."
David secretly chose 22, 23, and 24, and gave the sum 69. Again, in a couple of seconds, Jason said, "The dates are 22, 23, and 24."
Can you figure out Jason's trick?
