SOLUTION
1. Answer – 2. 256
Explanation :
32 * 8 = 256
256 * 4 = 1024
1024 * 2 = 2048

2. Answer – 5. 60
Explanation :
9 * 0.5 + 0.5 = 5
5 * 1 + 1 = 6
6 * 1.5 + 1.5 = 10.5
10.5 * 2 + 2 = 23
23 * 2.5 + 2.5 = 60

3. Answer – 3. 89
Explanation :
26 -17 = 9; 35 – 26 = 9
98 – 9 = 89

4. Answer – 3. 217
Explanation :
7 + 1³ – 1 = 7
7 + 2³ – 2 = 13
13 + 3³ – 3 = 37

5. Answer – 4.131
Explanation :
68 – 7 = 61; 61 – 7 = 54
124 + 7 = 131

6. Answer: c)
8 * 1 = 8 
8 * 5 = 40 
40 * 9 = 360
360 * 13 = 4680
4680 * 17 = 79560
The wrong term is, 4675

7. Answer: b)
182
+ 1 = 325
192
+ 1 = 362
202
+ 1 = 401
212
+ 1 = 442

8. Answer: a)
19 * 1 + 1 = 20
20 * 2 + 2 = 42
42 * 3 + 3 = 129
129 * 4 + 4 = 520
520 * 5 + 5 = 2605
The wrong term is 45

9. Answer: b)
72 * 0.5 + 1 = 37
37 * 1 + 1 = 38
38 * 1.5 + 1 = 58
58 * 2 + 1 = 117
117 * 2.5 + 1 = 293.5
293.5 * 3 + 1 = 881.5
The wrong term is, 293
