31. Find the next term of the following series.
1370 , 1320 , 1070 , -180 ?
Answer: -6430
Explanation:1370,1320,1070,-180,?
1370-50*(5^0)=1320
1320-50*(5^1)=1070
1070-50*(5^2)=-180
-180-50*(5^3)=-6430.
So next occurrence in series will be -6430.

32. Find the next term of the following series.
32,0.2,160,15,0.5,30,28,0.7,?
Answer: 40
Explanation:Break the series as below
32,0.2,160 / 15,0.5,30 / 28,0.7,?
32 / 0.2 => 320/2= 160,
similarly for next
15 / 0.5 => 150/5 = 30
28 / 0.7 => 280/7 = 40

34. Find the next term of the following series.
1,2,3,5,7,10,13,17,?
Answer: 21
Explanation:In the given series find the difference between numbers.
1, 2 difference = 1
2, 3 difference = 1
3, 5 difference = 2
5, 7 difference = 2
7, 10 difference = 3
10, 13 difference = 3
13, 17 difference = 4
So next number will be 17 + 4 = 21

36. Find the next terms of the following series.
33,8,41,46,21,67,72,47,119,124,?,?
Answer: 99,223
Explanation:Arrange the series as below
(33,8,41),(46,21,67),(72,47,119),(124,?,?)
For each group:
33 - 8 = 25
33 + 8 = 41
Similarly for other groups
46 - 21 = 25
46 + 21 = 67
so for next occurrence
124 - 25 = 99
124 + 99 = 223
