Safety standards require a pool to add 3 33 chlorine tablets to every 2 , 000 2,0002, comma, 000 gallons of water. Today, the lifeguards at Park Pool added 8 88 chlorine tablets to their pool's 10 , 000 10,00010, comma, 000 gallons of water. How does Park Pool's chlorine compare to the safety standards? Choose 1

, and

for

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

there are no answer choices

step-by-step explanation:

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
