• 72
  6-0=6
  6-6=0
  20-6=14(6+8)
  20-20=0
  42-20=22(14+8)
  42-42=0
  22+8=30
  8th position 42+30=72

• answer will be 72 as sereies will be 0,6,6,20,20,42,42,72 as difference between two is 6,0,14,0,22,0.... so difference is of 8 so next will be 6,0,14,0,22,0,30 so 42+30 is 72

• 6-0 = 6 = (6+0)
  6-6 = 0
  20-6 = 14 = (6+8)
  20-20= 0
  42-20= 22 = (14+8) then next term will be 42
  42-42= 0 end eighth term will be
  42+(22+8)= 72
  so ans. 72

• 72
  6-0=6
  each time the digits written twice
  20-6=14
  42-20=22
  
  now 14-6=8
  22-14=8
  
  so , the difference will be 22+8=30
  42 will be in 7th place.now 8th place 42+30=72
