Question

The sum of three consecutive natural numbers is 51. Find the numbers.

Answer 1

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

∴ x + (x + 1) + (x + 2) = 51
3x + 3 = 51
3x + 3 − 3 = 51 − 3 [Subtracting 3 from both the sides]
3x = 48
`(3x)/3=48/3` [Dividing both the sides by 3]
x = 16
Thus, the three natural numbers are x = 16, x+1 = 17 and x+2 = 18.
