Frogger the magic frog can jump 10 feet using his magical magic jump, but his magic loses its power by a half each time, so his next jump only goes as far as 5 feet. The next jump will take him 2.5 feet, and so on. How many jumps does it take to make it all the way across a 100-foot long pond?
Answer
He can’t make it to the other side. No matter how much he jumps, he will only travel about 20 feet at the most.
