A worm up a wall 20 feet high. Each day he climbs 5 feet at night he slips down 4 feet. How many days will it take the snail to get to the top of the wall. Thanks help!

Day 1: 0 + 5 - 4 = 1 foot
Day 2: 1 + 1 = 2 feet

And so on.

However -- watch what happens on day 15.
20 days:)
Hamza is wrong.

Make a chart as I did.

Watch what happens on day 16.
Hint: It goes up 5 feet a day.
