OpenStudy (anonymous):

that's all the question told me

OpenStudy (yttrium):

The question told you that the numbers are CONSECUTIVE INTEGERS, right? Therefore, if we let x as one of them, making it the lowest. The next numbers will be x+1 and x+2. You get it now?

OpenStudy (yttrium):

@matz199 do you get what I mean?

OpenStudy (anonymous):

yeah

OpenStudy (yttrium):

Therefore, what is the equation for the sum of that 3 consecutive integers?

OpenStudy (yttrium):

@matz199 ???
