The sum of three consecutive integers is 204 . What is the largest integer?

1st number > x
2nd number  > x+1
3rd number > x+2
x+x+1+x+2 = 204
3x = 207
x = 69
largest is 67
or
let the 3 numbers be (x1) , x , (x+1)
x1 + x + x+1 = 204
3x = 204
x = 68
largest number is 68+1 = 67
notice that in my second solution, the equation was somewhat easier to solve, but x represented the middle number.
