a1=x+y

a2=x-y

a3=x-3y

d=a2-a1 and d=a3-a2

d=x-y-[x+y] and d= x-3y-[x-y]

d=x-y-x-y and d=x-3y-x+y

d=-2y and d=-2y

Therefore, d=-2y

To find next four terms of an AP:

a4=a+3d                          a5=a+4d                             a6=a+5d

   =x+y+3[-2y]                      =x+y+4[-2y]                         =x+y+5[-2y]

   =x+y-6y                       a5 =x-7y                               a6=x-9y

a4 =x-5y                

                               a7=a+6d

                                    =x+y+6[-2y]

                                a7=x-11y

Hope it helps......
