- Question
Which Number would come in place of the underline mark in the series. 3, 9, 21, ___ , 93
Options- A. 39
- B. 45
- C. 48
- D. 51
- Correct Answer
- 45
ExplanationFirst difference is 6 and second is 12. But if we take third as 18, then fourth difference will be 24. Then 93 can not be the last term.
So we have to take the difference as 6, 12, 24 and 48.
So Answer is 21+24 = 45

Correct Answer: 125
Explanation:
The pattern is *2,*5/2,*2,*5/2,*2, . . . . .
So missing term is 50*(5/2)=125
Correct Answer: 2.0
Explanation:
The pattern is +0.05,+0.1,+0.15, . . . .
so missing term =1.8+0.20=2.0
Correct Answer: 96
Explanation:
The given number series is 52, 56, 48, 64, 32, ?
It follows a pattern that,
52
52 + 4 = 56
56 - 8 = 48
48 + 16 = 64
64 - 32 = 32
32 + 64 = 96
Therefore, the required next number in the given number series is 96.
Correct Answer: 1237
Explanation:
The given number series is 1, 3, 10, 41, 206, ?
It follows a pattern that,
1
1 x 2 + 1 = 3
3 x 3 + 1 = 10
10 x 4 + 1 = 41
41 x 5 + 1 = 206
206 x 6 + 1 = 1237
Hence, the next number in the given number series is 1237.
Correct Answer: 169
Explanation:
The given number series follows a pattern that, 4, 15, 37, 81, ?
4
4 + 11 = 15
15 + 22 = 37
37 + 44 = 81
81 + 88 = 169
Hence, the next number in the sequence is 169.
Correct Answer: c b c b
Explanation:
Here 'bccb' repeated 3 times.
b c c b | b c c b | b c c b
Correct Answer: 309
Explanation:
The pattern in the given series is +4, +9, +16, +25, ... i.e.
The next number is 284+25 = 309.
Correct Answer: 91
Explanation:
The given number series 9, 19, 21, 43, 45, ... follows a pattern that
ALternately (x 2 + 1) and (x 1 + 2)
9
9 x 2 + 1 = 19
19 x 1 + 2 = 21
21 x 2 + 1 = 43
43 x 1 + 2 = 45
45 x 2 + 1 = 91
Hence, the next number in the given sequence is 91.
Correct Answer: 24.75
Explanation:
The given number series is 22, 11, 33, 16.5, 49.5, ?
22
22 / 2 = 11
11 x 3 = 33
33 / 2 = 16.5
16.5 x 3 = 49.5
49.5 / 2 = 24.75
Hence, the next number series is 24.75.
Correct Answer: 23
Explanation:
The given number series 11, 12.2, 14.6, 18.2, ?
11
11 + 1.2 = 12.2
12.2 + 2.4 = 14.6
14.6 + 3.6 = 18.2
18.2 + 4.8 = 23
Hence, the next number in the given number series is 23.
