• 1st differences: 2, 8, 26, 80, x - 124
  2nd differences: 6, 18, 54, x - 204
  
  From here, I see that:
  6 = 6*1 = 6*(3^0)
  18 = 6*3 = 6*(3^1)
  54 = 6*9 = 6*(3^2)
  
  So the next 2nd difference after 54 could be 6*(3^3) = 162.
  That is, x - 204 = 162, so, x = 366.

• i guess 8+10=18,44+124=168

• 8+2 = 10
  
  10+8 i.e(8 = 2*3 + 2) = 18
  
  18+26 i.e(26 = 8*3 + 2) = 44
  
  44+80 i.e(80 = 26*3 + 2) = 124
  
  124+x i.e (x = 80*3+2= 242) = 366
  
  so ans is 366
