To Find: The terms of the sequence that represents the total number of stores at the end of each year from 2011 through 2015 and define if the sequence is approximately arithmetic.

Answer to Problem 78E
The total number of the stores is approximately arithmetic with the common difference of about
Explanation of Solution
Given:
The number of stores at end of 2010 at 2206 stores add the number of new stores for the year to the previous year to find the new total number of stores.
Calculation:
Consider the number of store at the end of 2011 is,
Consider the number of store at the end of 2012 is,
Consider the number of store at the end of 2013 is,
Consider the number of store at the end of 2014 is,
Consider the number of store at the end of 2015 is,
Thus, the total number of the stores is approximately arithmetic with the common difference of about
