Question

The sum of three consecutive odd numbers is 21. Find the numbers.
​

Answer 1

Step-by-step explanation:

Let one number be x.

Then, the other number will be x+2.

The third number = x+2+2=x+4

It is given that their sum is 21.

So, x+(x+2)+(x+4)=21

3x+6=21

3x=15

x=5

and x+2=7

x+4=9.
