step by step explanation please

Answer 1

Answer:let a natural number be x then other number will be ( x+1) and (x+2)

So x+1 + x+2 = 3x ( given)

X= 3

So the numbers will be 3 ,4,5

Sum of number will 3+4+5 = 12

Hope this will definitely help you

Step-by-step explanation:

Answer 2

Let 1st Number=x

Then 2nd Number=(x+1)

Then 3rd Number=(x+2)

Sum of Last two=(x+1)+(x+2)

=3×first=3x

A/Q

(x+1)+(x+2)=3x

2x+3=3x

3=3x-2x

x=3

We got X=3

Then All number=3,4,5

Check.

Sum of 4 and 5=3×3

9=9

Hence Right.

$\boxed{\mathbf{Numbers=3,4,5}}$
