Hi,         

Let x, (x+1) and (x+2) represent the three consecutive integers

question states***

  x  + (x+1) + (x+2)= 417  the equation that will determine the three integers



Solving for x

 3x + 3 = 417

    3x = 414

     x = 138, the first of the three consecutive integers

the three consecutive integers are 138, 139 and 140 



CHECKING our Answer

  138 +  139 + 140 = 417
