1,1,4,8,14,42,_
a)84,b)57,c)51,d)48

• (1*1)=1,1+3=4
  (4*2)=8,8+6=14
  (14*3)=42,42+9=51
  means every time multiply with 1,2,3 then add by 3,6,9 respectively

• answer must be 51...
  make it pair (1,1),(4,8),(14,48),(51,204)
  
  (1+0,1*1=1),
  (1+3=4,4*2=8),
  (8+6=14,14*3=42),
  (42+9=51,51*4=204
