    the the smallest of the consecutive number be \(n\) this makes the three consecutive integers \(n,n+1,n+2\) so the sum of them will be \[(n)+(n+1)+(n+2)\] and we know the sum is \(54\) so we have \[(n)+(n+1)+(n+2)=54\] simplify this and solve for \(n\)

    n+n+1+n+2=54 3n=54-1-2 3n=51 n= 17

    so by simply dividing, it wouldn't be the right answer, so u have to get a letter, and then get the formula

    you have found \(n=17\) and we set the consecutive integers to be \(n,n+1,n+2\) substitute \(n\) and you'll have the numbers

    I didn't know i had to do that...consecutive means...one after the other not the smallest

    yeah consecutive does mean one after the other finally you can check you solution does \(17+18+19=54?\)
