 here let p=a,q=a+r,r=a+2r,s=a+3r;


 then here p+q=2            =>2a+r=2


         also r+s=18           =>2a+5r=18


 solving we get r=4,a=-1;


p=-1, q=3, r=7, s=11


A=pq= -3, B=rs = 77;

I USE PUT & CHECK FORMULA IN THIS QUESTION.


P + Q = 2 , PQ=A ..............(1)


R + S = 18 , RS = B ...............(2)


-1,3,7,11 ARE IN A.P. SATISFYING THE RELATIONS (1) & (2)


SO , P=-1, Q=3 , R=7, S=11


SO, PQ= -3 = A


      RS= 77 = B
