• actual question is
  30.5,31,30,0,67.2,67,70,100,183.9,
  
  by round off,
  30.5=31
  183.9=184
  now the series becomes
  31,31,30,0,67,67,70,100,184,?
  ans is 184
  make pairs ,1st pair no difference
  2nd pair 30 is difference
  3rd pair no diff
  4th pair 30 is diff
  so last pair no diff should be there 184 is the ans or 183.9
  
  another approach

• (31+30)/2=30.5 , 30.5-30.5=0,
  (67+70)/2=68.5 , 68.5-67.2=1.3
  (183.9+x)/2=100+2.6 , so x =21.3
