Answers & Solutions:
1) Answer (B)
$2^4-2^2 = 16 – 4 = 12$
$3^4-3^2 = 81-9 = 72$
$4^4 – 4^2 = 256-16 = 240$
$5^4-5^2 = 625-25=600$
$6^4 – 6^2 = 1296-36= 1260$
Therefore, option B is the right answer.
2) Answer (D)
The given series consists of prime numbers from 641.
663 is divisible by 3.
665 is divisible by 5.
667 is divisible by 23.
669 is divisible by 3.
671 is divisible by 11.
673 is the next prime number after 661. Therefore, option D is the right answer.
3) Answer (C)
The given series is composed of 2 series.
12 ,21, 28, 33
12 + 9 = 21
21 + 7 = 28
28 + 5 = 33
84,77,68,?
84-7 = 77
77-9 = 68
68 – 11 = 57
Therefore, option C is the right answer.
4) Answer (A)
51*1 + 1 = 52
52*2 + 2 = 104+2 = 106
106*3 + 3 = 318+3 = 321
321*4 + 4 = 1284+4 = 1288
1288*5 + 5 = 6440+5 = 6445
Therefore, option A is the right answer.
5) Answer (E)
19 + 27 = 46
46 + 27 = 73
73 + 46 = 119
119 + 73 = 192
Therefore, option E is the right answer.
6) Answer (E)
254*0.5 + 1 = 127+1=128
128*1 + 2 = 128 + 2 = 130
130*1.5 + 3 = 195+3 = 198
198*2 + 4 = 396+4 = 400
400*2.5 + 5 = 1005
Therefore, option E is the right answer.
7) Answer (A)
$13^3 – 1 = 2197-1 = 2196$
$14^3 – 1 = 2744-1 = 2743$
$15^3 – 1 = 3375-1 = 3374$
$16^3 – 1 = 4096-1 = 4095$
$17^3 – 1 = 4913-1 = 4912$
Therefore, option A is the right answer.
8) Answer (E)
34 + 19 = 53
53 + 38 = 91
91 + 57 = 148
148 + 76 = 224
224 + 95 = 319
Therefore, option E is the right answer.
9) Answer (C)
52 + 1 = 53
53 – 4 = 49
49 + 9 = 58
58 – 16 = 42
42 + 25 = 67
67 – 36 = 31
Therefore, option C is the right answer.
10) Answer (D)
The difference between 2 consecutive terms in the series is a prime number.
62 + 2 = 64
64 + 3 = 67
67 + 5 = 72
72 + 7 = 79
79 + 11 = 90
90 + 13 = 103
103 + 17 = 120
Therefore, option D is the right answer.
11) Answer (A)
First term = $1^2 + 1 = 2$
Second term = $2^2 + 2 = 6$
Third term = $3^2 + 3 = 12$
Fourth term = $4^2 + 4 = 20$
So, fifth term = $5^2 + 5 = 30$
Hence, option A is the correct answer.
12) Answer (C)
First term = $1 * 2 * 3 = 6$
Second term = $2 * 3 * 4 = 24$
Third term = $3 * 4 * 5 = 60$
Fourth term = $4 * 5 * 6 = 120$
So, fifth term = $5 * 6 * 7 = 210$
Hence, option C is the correct answer.
13) Answer (B)
First term = $10$
Second term = $10 – 2.5 = 7.5$
Third term = $7.5 – 2 = 5.5$
Fourth term = $5.5 – 1.5 = 4$
Fifth term = $4 – 1 = 3$
So, sixth term = $3 – 0.5 = 2.5$
Hence, option B is the correct answer.
14) Answer (C)
First term = $5 * 1 = 5$
Second term = $5 * 1.5 = 7.5$
Third term = $7.5 * 2 = 15$
Fourth term = $15 * 2.5 = 37.5$
So, fifth term = $37.5 * 3 = 112.5$
Hence, option C is the correct answer.
15) Answer (A)
First term = $1^2 = 1$
Second term = $2^3 = 8$
Third term = $3^2 = 9$
Fourth term = $4^3 = 64$
Fifth term = $5^2 = 25$
So, sixth term = $6^3 = 216$
Hence, option A is the correct answer.
16) Answer (A)
First term = $7 * 1 = 7$
Second term = $7 * 2 = 14$
Third term = $14 * 3 = 42$
Fourth term = $42 * 4 = 168$
So, fifth term = $168 * 5 = 840$
Hence, option A is the correct answer.
17) Answer (C)
First term = $1^2 + 2^2 = 5$
Second term = $3^2 + 4^2 = 25$
Third term = $5^2 + 6^2 = 61$
Fourth term = $7^2 + 8^2 = 113$
So, fifth term = $9^2 + 10^2 = 181$
Hence, option C is the correct answer.
18) Answer (B)
First term = $3$
Second term = $5 – 1 = 4$
Third term = $4 – 2 = 2$
Fourth term = $2 – 3 = -1$
So, fifth term = $-1 – 4 = -5$
Hence, option B is the correct answer.
19) Answer (B)
First term = $1^2 + 1^3 = 2$
Second term = $2^2 + 2^3 = 12$
Third term = $3^2 + 3^3 = 36$
Fourth term = $4^2 + 4^3 = 80$
So, fifth term = $5^2 + 5^3 = 150$
Hence, option B is the correct answer.
20) Answer (A)
First term = $17$
Second term = $17 + 2 = 19$
Third term = $19 – 3 = 16$
Fourth term = $16 + 4 = 20$
Fifth term = $20 – 5 = 15$
So, sixth term = $15 + 6 = 21$
Hence, option A is the correct answer.
