There is a frog dead in the centre of the pond on a lily pad. The pond is 7 metres in diameter. There are 6 lily pads leading to the edge, which the frog must jump onto if he wishes to get out. The frog can only jump to 3 pads each day. How many days will it take him to get to the edge of the pond?

Answer
He will never get out as he is “dead”.
