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

30.5,31,30 ,0, 67.2,67,70 ,100, 183.9,?,?
Answer :

(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
