While happily jumping in the forest a frog fell into a hole, 14 1/2 feet deep. It could jump up 3 feet, but it slid back 1 foot each time it jumped.
How many jumps does it take it to get out of the hole?

Oops, forgot the spoiler 😳

Spoiler

The frog would never get up, because it keeps going down the hole, not up it.

He started with $1,500 dollars and would have to wait 35 years. The frog would have to jump seven times.
