    If x-1, x-4 and x-7 are in AP

    then x-4 will be average of x-1 and x-7

    [(x-1)+(x-7)]*1/2=x-4

    2x-1-7=2(x-4)

    2x-8=2x-8

    2x-2x=-8+8

    0=0

    Hence there is no solution

    Statement in your question is not a question this shows that

    x-1, x-4 and x-7 are in AP  for all real values of x

    So x =.-infinite........-5,-4,-3,-2,-1,0,1,2,3.......................infinite
