<PRE><B>Question 800599</B>
Problem: The average of a set of four integers is 14. When a fifth number is included in the set, the average of the set increases to 16. What is the 5th number? 
-----------------------------
Sum of the 4 integers is 4*14 = 56
--------
Equation:: (56+x)/5 = 16
56+x = 80
x = 24 (the 5th number)
-------------------------
