Question

The sum of three consecutive even integers is 312. What are the integers?

Answer 1

`" "102,104,106`

Explanation:

`" let "2x=" the middle number"`

`"the first number is then "2x-2`

`"the last number "2x+2`

so

`2xcancel(-2)+2x+2x+cancel(2)=312`

`6x=312`

`x=312/6=52`

`2x=2xx52=104`

`2x-2=104-2=102`

`2x+2=104+2=106`
