Question

The sum of 3 consecutive odd numbers is 27, how do you find the numbers?

Answer 1

Remember that consecutive integers differ in the value of `2`:

Let the first no. be `x`:
Then,second no.=`x+2`
Third no.=`x+4`

So,

`rarr(x)+(x+2)+(x+4)=27`

`rarrx+x+2+x+4=27`

`rarr3x+6=27`

`rarr3x=27-6`

`rarr3x=21`

`x=21/3=37`

So,First no=`x=7`
Second no.=`x+2=7+2=9`
Third no.=`x+4=7+4=11`

The three nos. are `7,9 and 11`
