The sum of three consecutive natural numbers is 36. What are the numbers?

Let the three consecutive natural numbers be x,x + 1,x + 2.

Their sum = 36


⇒ x + x + 1 + x + 2 = 36


⇒ 3x + 3 = 36


⇒ 3x = 36-3


⇒ 3x = 33


⇒


⇒ x = 11


Hence, the required three consecutive numbers are 11 ,11 + 1,11 + 2 = 11,12 and 13.
