Question

A snail is at the bottom of a 20 meters deep pit. Every day the snail climbs 5 meters upwards, but at night it slides 4 meters back downwards.

Answer 1

What is the question asking?

Answer 2

(5 -4) d = 20
-> d= 20 days to clim up to the surface

Answer 3

yep

Answer 4

Actually the way I see it he should get out on day 16, because he starts day 16 at a height of 15m. If he climbs 5m that day he gets out, and won't slide back down.

Answer 5

oh yes sorry turing test is right
On the first day, the snail reaches a height of 5 meters and slides down 4 meters at night, and thus ends at a height of 1 meter.
On the second day, he reaches 6 meters, but slides back to 2 meters.
On the third day, he reaches 7 meters, but slides back to 3 meters.
...
On the fifteenth day, he reaches 19 meters, but slides back to 15 meters.
On the sixteenth day, he reaches 20 meters, so now he is at the top of the pit!
Conclusion: The snail reaches the top of the pit on the 16th day!...
