A snailis trying to climb up a cup left by some students that littered.Each hour the snail slithers up 2`` but when he is tired he sleeps and slides 1``.
How many hours until he reaches the top of the cup with a height of 10 is this an integer question?

MathMate,
Problems of this kind can be readily solved by the simple case of 2" in which case the snail gets out in 1 hour.
How much more time it takes him to climb an extra inch? Extra 8 inches?
