Question 21
Jack has 140 candies. He eats 1 on the first day and aims to eat three times as many as the preceding day on each following day. On the final day, if fewer than that target remain, he eats all the remaining candies. How many candies does he eat on the final day?
The source omits a final-day exception although its solution uses one. Here the tripling rule stops when fewer candies remain than the next target, and Jack eats that remainder.
