Question

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

Answer 1

Answer:

9,10,11

Step-by-step explanation:

x+(x+1)+(x+2)=30

3x+3=30

3(x+1)=30

(x+1)=10

x=9

The numbers are 9,10,11.

Answer 2

Answer :

• The first consecutive natural number = 9.
• The second consecutive natural number = 10.
• The third consecutive natural number = 11.

Given :

• The sum of three consecutive natural numbers = 30.

To Find :

• Three consecutive natural numbers.

Solution :

Let,

The first consecutive natural number be x.

The second consecutive natural number be x + 1.

The third consecutive natural number be x + 2.

Given,

Sum of all consecutive natural numbers is 30.

So,

=> x + (x + 1) + (x + 2) = 30

=> x + x + 1 + x + 2 = 30

=> x + x + x + 1 + 2 = 30

=> 3x + 3 = 30

=> 3x = 30 - 3

=> 3x = 27

=> x = 27/3

=> x = 9

∴ x = 9

So, the all consecutive natural numbers are :-

First consecutive natural number = x = 9.

Second consecutive natural number = x + 1 = 9 + 1 = 10.

Third consecutive natural number = x + 2 = 9 + 2 = 11.

Hence,

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