Answer» x is an integer. So,it is of the form 3k,3k+1 or 3k+2 where k is an integer. If x=3k,then x+1=3k+1,not divisible by 3 x+2=3k+2,not divisible by 3 If x=3k+1(not divisible by 3),then x+1=3k+2,not divisible by 3 x+2=3k+3=3(k+1), divisible by 3 If x=3k+2(not divisible by 3),then x+1=3k+3=3(k+1),divisible by 3 x+2=3k+4=3(k+1)+1,not divisible by 3 Hence by seeing all the above cases,we can safely say that:out of x,x+1 and x+2,only one is divisible by 3.
