Josh wanted to buy a bike but didn't have enough money. Sam Slick said, "I can fix that. Each time you jump that fence, I'll double your money. There's one small thing though. Each time I pay you, you must give me $\$ 48$ back for the privilege of jumping." Josh agreed, jumped the fence, received his payment from Sam Slick, and paid Sam $\$ 48$ . Repeating the routine 2 more times, Josh was distressed to find that, on the last jump, after Sam had made his payment to Josh, Josh had only $\$ 48$ with which to pay Sam and so had nothing left.
