The average of five numbers is 43. If four of the numbers are 37, 48, 39 and 45, what is the fifth number?

 First I added up all the numbers that were given .I got 169. Then I added each  of  the numbers that were possible answer choices .Then I divided each number by 5 to see which one will be 43 then it was 46.
