A company can buy packages of 500 sheets of paper for four dollars at that rate how much paper can be bought for $2000

250,000

Step-by-step explanation:

500/4=125

125 sheets per dollar

2000 x 125= 250,000

250,000 sheets of paper can be bought with $2000

, 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
