Problem
The sum of six consecutive positive integers is 2013. What is the largest of these six integers?
Solution 1
The mean of these numbers is 
. Therefore the numbers are 
, so the answer is 
Solution 2
Let the 
number be 
. Then our desired number is 
.
Our integers are 
, so we have that 
.
Solution 3
Let the first term be . Our integers are 
. We have, 
Solution 4
Since there are 
numbers, we divide 
by to find the mean of the numbers. 
.
Then, 
(the fourth number). Fifth: 
; Sixth: 
.
Solution 5
Let the 
number be . Then our list is: 
. Simplifying this gets you 
, which means that
