The equation 20 + 5x = y represents the amount of money in a bank account, y, after x weeks of deposits. Which equation represents the
same equation, solved for x

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

, 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

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

a is the best answer choice
