E A D
K I H
Z ? U

what replaces ?

• first we will take first series
  E K Z(by row wise)
  the diff b/e E AND K IS 5
  the diff b/W K AND Z IS 14
  SO diff of 9
  now we will take 3rd series
  D H U
  the diff b/W D AND H IS 3
  the diff b/W H AND U IS 12
  SO diff of 9
  so likewise in second series
  A I ?
  the diff b/W A AND I IS 7
  SO NEXT TERM AFTER I WILL BE Z(DIFF OF 16)
  SO IT WILL MAKE A DIFFERENCE OF 9
  SO LAST TERM WILL BE LIKE THIS
  E A D
  K I H
  Z Z U

• In alphabet e=5, a=1, d=4, k=11, i=9, h=8 z=26, u=21
  now (5-4)^2=1 and (11-8)^2=9
  so(26-21)^2=25
  now 25 number alphabet is y
  ans= y
