Question

a rabbit falls into a dry well 30 meters deep. since being at the bottom of a well she tries to go up 3 meters but falls down 2 meters. how many days does it take her to get out of the well?

Answer 1

I believe the correct answer is the 27th day, since it goes up three each day and down 2 each day.  Kinda like this

Day 1: Up 3 - 2 = 1

Day 2: Your starting point is now 1.  1 + 3 - 2 = 2

And then it would keep on going up by ones until you reached day 27.  Then it will be Day 27: 27 + 3 - 2.  However on that day the rabbit would've already reached the top of the well and would not have slid down the two meters.  Hope this long kinda confusing explanation is correct and helpful.
