Please help. 

The average of 3 numbers is 14. The average of 2 of the numbers is 19. What is the third number?


Since the average of the three numbers is 14, then the sum of the 3 numbers is: 3 * 14, or 42


Since the average of 2 of the three numbers is 19, then the sum of 2 of the 3 numbers is: 2 * 19, or 38


The third number is: 42 - 38, or {{{highlight_green(4)}}}
