If the frog jumps up 3 feet and then loses 2 feet, he will hit the three foot mark on his 1st jump, the four foot mark on his second jump, etc. So, he will hit the 12 foot mark on his tenth jump(and the slip back two feet) You can change the depth of the well to any number and it will always be two jumps less than the depth. So a 50 foot depth...48 jumps. 100 foot depth...98 jumps
As least, that's my way of figuring it out.
That was fun, Tal. Thanks for posting.
