The average of five consecutive odd numbers is 51. What is the difference between the highest and lowest number? Pick one.
A) .8 B) 9 C) 6 D) 5 E) 2
Explanation:   Let the numbers be x, x + 2, x + 4, x + 6 and x + 8.   Then, [x + (x + 2) + (x + 4) + (x + 6) + (x + 8)] / 5 = 51   5x + 20 = 255   x = 47   So, required difference = (47 + 8) – 47 = 8   .8NSWER: .8
