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.

It will never reach even 20 feet.

10+5+2.5+1.25+.625.... which is always less then 20 so frog can never able to cross the pond.
