Sally has a pet snail that fell into a well the well is 16 feet deep each day the snail climbs up 5 feet but each night it slides back diown 4 feet how many days will it take for sallys snail to get to the top of the well

12 days

Step-by-step explanation:

Sally has  pet snail that fell into a well.

Depth of the well = 16 feet

Snail climbs up 5 feet but each night it slides back down 4 feet.

So the snail climbs up per day = 5 feet - 4 feet = 1 feet.

Number of days snail took to reach at 11 feet = 11 × 1 = 11 feet

Remaining distance to cover by the snail = 16 - 11 = 5 feet

Number of days to cover remaining 5 feet to reach the top of the well = 1 day

Therefore, snail will take 12 days to reach the top of the well.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
