solution

1. (c) The above series is actually the prime no. ones. Here each prime no. starting from 11 would get multiplied by 2. 11 × 2 = 22 13 × 2 = 26 17 × 2 = 34 ………… 41 × 2 = 82 43 × 2 = 86 Hence, option (c) is correct.

2. (d) The above series follows a multiplication pattern 1 × 2 = 2 3 × 4 = 12 5 × 6 = 30 …………… 11 × 12 = 132 13 × 14 = 182 Hence, option (d) is correct

3.b

4. (b) The above series follows the pattern given below :- 1 × 1 = 1 2 × 2 = 4 4 × 4 = 16 8 × 8 = 64 …………… 64 × 64 = 4096 Hence, option (b) is correct.

5. (e) In the above series, the numbers follows this pattern:-
9 + 5 = 14; 14 – 2 =12
12 + 5 = 17; 17 – 2 = 15
15 + 5 = 20;  20 –2 = 18
18 + 5 = 23;  23 – 2 = 21
Hence, Option (e) is the answer. Here actual answer is 23, 21

6. a
7.d

8.(c) In the above series, the next term is derived from previous one in certain pattern: –
=> 4 = 1 × 1 + 3
14 = 4 × 2 + 6
51 = 14 × 3 + 9 and so on.
Here, consider term 218
=> Now according to above pattern,
=> 51 × 4 + 12Þ
=>216 should come, but 218 is being wrongly inserted
Hence, option (c) is correct

9.e

10. (c); In the above mentioned series, the next term is derived from previous one by dividing a no. following a certain pattern.
=>630  3.5 = 180
=>180  3 = 60
=>60 2.5 = 24
Here instead of 26, 24 should come in above series.
Hence, option (c) is correct.
