The sum of five consecutive numbers is 190. What is the sum of the largest and the smallest number?
76
From the question,
x + x + 1 + x + 2 + x + 3 + x + 4 = 190
Or 5x + 10 = 190
Or 5x = 190 - 10
Or x = 1805 = 36
∴ smallest number = x = 36
and largest number = x + 4 = 36 + 4 = 40
∴ Smallest number + Largest number = 36 + 40 = 76
