Solution:
1). C)The series is +(10 x 1 + 12), +(10 x 2 + 22), +(10 x 3 + 32), +(10 x 4 + 42), 
+(10 x 5 + 52),…..
ie 28 + 10 x 1 + 12 = 39,
39 + (10 x 2 + 22) = 63,
63 + (10 x 3 + 32) = 102,
102 + (10 x 4 + 42) = 158,
158 + (10 x 5 + 52) = 233, …
2). E)The series +32, +53, +72, +93, +112, +133, …
 ie 7 + 32= 16, 16 + 53= 141, 141 + 72= 190, 190 + 93 = 919, 919 + 112= 1040, …
3). C)The series is +(5 x 1), +(5 x 3), +(5 x 5), +(5 x 7), +(5 x 9),….
 ie 12 + (5 x 1) = 17, 17 + (5 x 3) = 32, 32 + (5 x 5) = 57, 57 + (5 x 7) = 92, 92 + (5 x 9) = 137,
4). D)The series is +22 + 2, +42 + 4, +62 + 6, +82+ 8, +102 + 10, …
 ie 19 + 22 + 2 = 25, 25 + 42+ 4 = 45, 45 + 62 + 6 = 87, 87 + 82 + 8 = 159, 159 + 102+ 10 = 269, …
5). E)The series is +41, +82, +164, +328, +656,….
 ie 83 + 41 = 124, 124 + 82 = 206, 206 + 164 = 370, 370 + 328 = 698, 698 + 656 =1354,…..
6). E)The series is 78 + 73 = 421
 421 – 83 = -91, -91 + 93= 638, 638 -103 = -362, -362 + 113 = 969,

7). C)The series is


8). D) The series is


9). B)The series is 740 x (1/2) – 2 =368,
368 x (1/2) -3 =181, 181x (1/2) – 4 =-86.5, 86.5 x (1/2) = 38.25, 38.25 x (1/2) – 6= 13.125

10). D)The series is x6 + 1, x5 + 2, x4 + 3, ×3 + 4, x2 + 5,… …
