1)30.5,31,30.3,67.2,67,70,100.183,?
Ans:
Questions will be like this->30.5,31,30,0,67.2,67,70,100,183.9,? This is from round off
30.5->31
67.2->67
67->70
70->100
183.9->184(Ans)
(round off)

2)11.5,17.5,35.5,89.5.?
Ans:
11.5-17.5 = 6 = 3* (2*1)
17.5-35.5 = 18 = 3*(2*3^1)
25.5-89.5 = 54 = 3*(2*3^2)
89.5-251.5 = 162 = 3*(2*3^3)
ans : 251.5

3)1/3,1/2,1/4,2 1/3,3 1/2,4 1/4,4 1/3 ,6 1/2,?
Ans:
Series like:(1/3, 2 1/3, 4 1/3),(1/2, 3 1/2 , 6 1/2),(1/4, 4 1/4 , ?)->ans will be 8 1/4 ,
increases by 4.

4)6.5,8,8,12,9.5,24,11,36,?
Ans:
look at the alternate series:
6.5+1.5=8,
8+1.5=9.5 ,
9.5+1.5=11 ,
11+1.5,=12.5.(Ans)

5)198,194,184,168,146,?
Ans:
198-4=194,
194-(4+6)=184,
184-(4+6+6)=168,
168-(4+6+6+6)=146
146-(4+6+6+6+6)=118(Ans)

6)30,28,25,20,34,28,?
Ans:Look at the alternate series 30,25,34,? another series will be 28,20,28,20.....
So now, 30-5=25
25+9=34
34-5=29(Ans)

7)18,20,22,20,28,20,?
Ans:Two series:18,22,28,? and another alternate series is 20,20,20....
18+4=22
22+6=28
28+8=36(Ans)


8)11,8,17,14,23,24,31,32,?
Ans:
Prime number series:11,13-5,17,19-5,23,29-5,31,37-5,41(Ans)

9)9,18,21,25,20,?
Ans:
9 + 3^2 = 18(next term)
21 + 2^2 = 25
20 + 1^2 = 21(Ans)


10)1370,1320,1070,-180.?
Ans:
1370-50=1320,
1320-(50*5)=1070,
1070-(250*5)=-180,
-180-(1250*5)=-6430(Ans)

198,194,184,168,146,
198-4=194
194-10=184
184-16=168
168-22=146
146-28=118
(4+6=10,10+6=16,16+6=22,22=6=28......s0 just adding 6 to difference)
