Solution With Answer Key:
1). B)
 The series is +33 , +32, +23, +22, +13, +12, …..
125 + (3)3 = 152 ;   152 + (3)2 = 161 ;  161 + (2)3 = 169;   169 + (2)2 = 173
173 + (1)3 = 174;   174 + (1)2 = 175

2). C)
The series is x2, x3, x4, x5, x6,….
 27 × 2 = 54;  54×3 = 162;  162 × 4 = 648;   648 × 5 = 3240
3240 × 6 = 19440

3). C)
The series is x2 — 21, x2 — 22, x2 - 23, x2 - 24, ...
ie 161 x 2 — 2 = 320,
320 x 2 — 22 = 636,
636 x 2 — 23 = 1264,
1264 x 2 — 24 = 2512,
2512 x 2 — 25 = 4992,

4). B)
The series is 632 + 63 = 4032,
652 + 65 = 4290, 672 + 67 = 4556,
692 + 69 = 4830, 712 + 71 = 5112,
732 + 73 = 5402, ...

5). E)
 The series is
16 x 4 + 8 = 72
72 x 4 + 8 = 296
296 x 4 + 8 = 1192
1192 x 4 + 8 = 4776
4776 x 4 + 8 19112

6). B)
The series is —(5)2, +(7)2 - (9)2, +(11)2, —(13)2….
 ie 584 — 52 = 559,
 559 + 72 = 608,
608 - 92 = 527,
527 + 112 = 648,
648 — 132 = 479,

7). D)
The series is
36 x 2.5 = 90
90 x3.5 = 315
315 x4.5 = 1417.5
1417.5 x5.5 = 7796.25
7796.25 x6.5 = 5.675.625

8). A)
The series is x1 + 12, x2 + 22, x3 + 32, x4 + 42,
je 28 x 1 + 12= 29,
29 x 2 + 22 = 62,
62 x 3 + 32 = 195,
195 x 4 + 42 = 796,
796 x 5 + 52 = 4005,

9). C)
The series is x2 + 10, x2 — 10, x2 + 10, x2 - 10, ...(repeated alternately)
 ie 15 x 2 + 10 = 40,
40 x 2 — 10 = 70,
70 x 2 + 10 = 150,
150 x 2 — 10 = 290,
290 x 2 + 10 = 590,

10). E)
 The series is 205 + (28)2 = 989,
989 - (25)2 = 364,
364 - (22)2 = 848.
848 — (19)2 = 487,
487 + (16)2 = 743,
