The average of five consecutive odd numbers is 37. What is the sum of the highest and the lowest number?
Answer & explanation
Correct answer: option 2
Let 'a' be any odd number
Sum of 5 consecutive odd numbers = 37
{\(\frac{a + (a+2) + (a+4)+ (a+6)+ (a+8)}{5}\)} = 37
5a + 20 = 185
5a = 165
a = 33
Sum = Lowest Number + Highest number
Sum = a+(a+8)
Sum = 33+33+8 = 74
