Question 20
Jack has 80 candies. He eats 1 on the first day. Each following day he plans to eat twice as many as the previous day, until all the candies are gone. How many candies does he eat on the last day?
On the last day, if fewer candies remain than the planned doubled amount, Jack eats only the remainder. This is the intended exception used by all three source answers.
