A snail decides to climb a 12 meter well. Every day, he climbs 3 meters in the daytime and slides 2 meters at night. After how many days will he finally arrive at the other side of the well?

Suppose that the rate at which the snail traveled decreased at a nonconstant rate depending upon how long he had been traveling, and also depending upon the amount of salt being poured on him? :P

H(n)=3+(n1), where H is height after n days. Since you want H(n)=10, I think you can do the rest.
