Question

Sum of three consecutive numbers is 48. Find the numbers​

Answer 1

Dividing

48/3=16

Explanation:

This is the middle number. The others are one less and one more:

15,16,17

In addition, there is another way to solve this.

For instance, you know that the sum of three numbers must add to be 48. Also, you know that they are consecutive.

Thus, you can represent the value of the least number with x.

Moreover, since they are consecutive numbers you can represent the value of the next number with x+1

.

Now, for the third number you simply add 2 ( x+2).

The equation would look something like this:

(x)+(x+1)+(x+2)=48

3x+3=48

+3 on both sides

3x=45

divide by 3

x=15

Substitute for the other values when

x=15

x+1→15+1=16

x+2→15+2=17

Finally, the three answers are

15,16 and 17

hope it helps...

Answer 2

Answer :

Let smallest number be x .

Then, 2nd number = x+1

          3rd number = x+2

So, ⇒ x + (x+1) + (x+2) =  48

     ⇒      3x  +  3         =   48

     ⇒          3x             =   48 - 3

     ⇒          3x             =    45

     ⇒           x              =    45 ÷ 3

     ⇒           x              =     15
