B. 150
C. 125
D. 92
E. 75

Explanation: The pattern of the given series can be explained as,

2              5              11           23           44           77           125

+3           +6            +12          +21        +33          +48

+3            +6            +9           +12         +15

125 will come in the place of “?”

2. 7, 13, 21, 31, 43, ?
A. 57
B. 67
C. 87
D. 97
E. 48

Explanation:

Considering the above series,

7, 13, 21, 31, 43, ?

The logic of the series can be explained as,

2 × 3 + 1 = 7

3 × 4 + 1 = 13

4 × 5 + 1 = 21

5 × 6 + 1 = 31

6 × 7 + 1 = 43

By observing the pattern, we can write

7 × 8 + 1 = 57

⇒ ? = 57

∴ The value of ? is 57.

3. 144, 164, 194, 234, 284, ?
A. 400
B. 344
C. 564
D. 356
E. 369

Explanation:

The series follows following pattern:

⇒ 144 + 20 = 164

⇒ 164 + 30 = 194

⇒ 194 + 40 = 234

⇒ 234 + 50 = 284

By observing the pattern, we can write

284 + 60 = 344

⇒ ? = 344

∴ The value of? is 344.

4. 3, 9, 27, 57, 99, ?
A. 149
B. 150
C. 151
D. 152
E. 153

Explanation:

Considering the above series,

3, 9, 27, 57, 99, ?

The logic of the series can be explained as,

9 – 3 = 6 = (6 × 1)

27 – 9 = 18 = (6 × 3)

57 – 27 = 30 = (6 × 5)

99 – 57 = 42 = (6 × 7)

By observing the pattern, we can write

? – 99 = 54 = (6 × 9)

⇒ ? = 153

∴ The value of ? is 153.

5. 180, 174, 162, 144, 120, ?
A. 50
B. 60
C. 70
D. 80
E. 90

Explanation:

Considering the above series,

180, 174, 162, 144, 120, ?

The logic of the series can be explained as,

180 – (6 × 1) = 174

174 – (6 × 2) = 162

162 – (6 × 3) = 144

144 – (6 × 4) = 120

By observing the pattern, we can write

120 – (6 × 5) = 90

⇒ ? = 90

∴ The value of? is 90.

Directions:(6-10) Find the wrong term in the series.

6. 150, 290, 560, 1120, 2140, 4230, 8400
A. 2140
B. 560
C. 1120
D. 4230
E. 290

Explanation: The pattern of the number series is:

150 × 2 – 1 × 10 = 290

290 × 2 -2 × 10 = 560

560 × 2 – 3 × 10 = 1090 ≠ 1120

1090 × 2 – 4 × 10 = 2140

2140 × 2 – 5 × 10 = 4230

Hence 1120 is wrong Number.

7. 19, 68, 102, 129, 145, 154
A. 154
B. 129
C. 145
D. 102
E. None of these

Explanation: The pattern of the number series is:

19 + 72 = 68

68 + 62 = 104 ≠ 102

104 + 52 = 129

129 + 42 = 145

145 + 32 = 154

Hence 102 is wrong Number.

8. 12, 237, 406, 527, 604, 657
A. 657
B. 237
C. 406
D. 527
E. 604

Explanation: The given number series is based on the following pattern.

12 + 152 = 237

237 + 132 = 406

406 + 112 = 527

527 + 92 = 608

608 + 72 = 657

Hence 604 is the wrong term.

9. 636, 689, 746, 803, 864, 930
A. 636
B. 689
C. 746
D. 803
E. 930

Explanation: The series follows the following pattern:

25+ 11 = 636

26+ 13 = 689

27+ 17 = 746

28+ 19 = 803

29+ 23 = 864

30+ 29 = 929 ≠ 930

∴ 930 is the wrong term.

10. 27 , 36 , 51 , 68 , 87, 110
A. 110
B. 36
C. 51
D. 68
E. 87

Explanation: Here the logic follows as the addition of prime numbers from 11

27 + 11 = 38 (36 is wrong)

38 + 13 = 51

51 + 17 = 68

68 + 19 = 87

87 + 23 = 110

36 is the wrong term
