Answer 2

Given :-

• Sum Of 3 Consecutive Numbers = 72.

To Find :-

• 3 Numbers.

Solution :-

Note :- 3 Numbers are Consecutive that means they are line wise. Eg. 1-2-3-4 etc.

☯️ Let,

1st Number = x.

2nd Number = x + 1.

3rd Number = x + 2.

Now, According To The Question,

⇒ x + x + 1 + x + 2 = 72.

⇒ 3x + 3 = 72.

⇒ 3x = 69.

⇒ x = 69/3.

⇒ x = 23.

Now,

• 1st Number = x = 23.

• 2nd Number = x + 1 = 24.

• 3rd Number = x + 2 = 25.
