Riddle # 197 (Solved By dangerous tears)

[naz]

The frog fell into a hole that was 14 1/2 feet deep. He could jump 3 feet, but he slid back a foot each time he jumped. How many jumps does it take him to get out of the hole?

[DaNgErOuS tEaRs]

The frog advances 2 feet with each jump, but he jumps 3 feet, so the 7th jump, starting at 12 feet, brings him to 15 feet, which takes him out of the hole
