The sum of three consecutive natural numbers is 30.Find the numbers.
​

Answer 1

The three consecutive natural numbers are 9,10 and 11.

Step-by-step explanation:

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

It is provided that the sum of these three numbers is 30.

Compute the value of x as follows:

x + x + 1 + x + 2 = 30

              3x + 3 = 30

             3(x + 1) = 30

                 x + 1 = 10

                      x = 9

The numbers are:

x = 9

x + 1 = 10

x + 2 = 11

Check:

9 + 10 + 11 = 30

Thus, the three consecutive natural numbers are 9,10 and 11.
