Five gal of water are added to a pool each minute. after correctly carrying out the solve step of the five-step problem-solving plan, which solution should you arrive at to find the number of minutes that must pass until the pool contains 80 gal of water? drag and drop the correct answer into the box for the question.

It would take 16 minuets to fill the pool with 80 gallons.

Step-by-step explanation:

Five gal of water are added to a pool each minute.

The number of minutes that must pass until the pool contains 80 gal of water will be = minutes.

So, it would take 16 minuets to fill the pool with 80 gallons.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

answer:

a=9
