QUESTION: 1

In this questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the black spaces.

**Q. 1, 4, 9, 16, 25, (____)**

Solution:

1st term = 1^{2} = 1

2nd term = 2^{2} = 4

3rd term = 3^{2} = 9

4th term = 4^{2} = 16

5th term = 5^{2} = 25

**Thus, Missing number = 6 ^{2 }= 36**

QUESTION: 2

In this questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the black spaces.

**Q. 20, 19, 17, (____), 10, 5**

Solution:

1st term = 20 - 0 = 20

2nd term = 20 - 1 = 19

3rd term = 19 - 2 = 17

4th term = 17 - 3 = 14

5th term = 14 - 4 = 10

6th term = 10 - 5 = 5

**Thus, Missing number is 4th term = 14**

QUESTION: 3

In this questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the black spaces.

**Q. 2, 3, 5, 7, 11, (____), 17**

Solution:

Clearly, the given series consists of prime numbers starting from 2. The prime number after 11 is 13.

**Thus, the missing number is 13.**

QUESTION: 4

**Q. 6, 11, 21, 36, 56, (____)**

Solution:

1st term = 6

2nd term = 6 + 5 = 11

3rd term = 11 + 10 = 21

4th term = 21 + 15 = 36

5th term = 36 + 20 = 56

**Thus, Missing Number is 6th term = 56 + 25 = 81**

QUESTION: 5

**Q. 3, 9, 27, 81, (____)**

Solution:

1st term = 3 * 1 = 3

2nd term = 3 * 3 = 9

3rd term = 3 * 9 = 27

4th term = 3 * 27 = 81

**Thus, Missing number is 5th term = 3 * 81 = 243**

QUESTION: 6

Q. 2, 5, 9, (___), 20, 27

Solution:

1st term = 2

2nd term = 2 + 3 = 5

3rd term = 5 + 4 = 9

4th term = 9 + 5 = 14

5th term = 14 + 6 = 20

6th term = 20 + 7 = 27

**Thus, Missing number is 4th term = 14**

QUESTION: 7

**Q. 5, 9, 17, 29, 45, (____)**

Solution:

1st term = 5

2nd term = 5 + (4*1) = 5 + 4 = 9

3rd term = 9 + (4*2) = 9 + 8 = 17

4th term = 17 + (4*3) = 17 + 12 = 29

5th term = 29 + (4*4) = 29 + 16 = 45

**Thus, the missing number is 6th term = 45 + (4*5) = 45 + 20 = 65**

QUESTION: 8

**Q. 1, 6, 15, (____), 45, 66, 91**

Solution:

1st term = 1

2nd term = 1 + 5 = 6

3rd term = 6 + (5+4) = 6 + 9 = 15

4th term = 15 + (9+4) = 15 + 13 = 28

5th term = 28 + (13+4) = 28 + 17 = 45

6th term = 45 + (17+4) = 45 + 21 = 66

7th term = 66 + (21+4) = 66 + 25 = 91

**Thus, the missing number is 4th term= 15 + (9+4) = 15+13 = 28**

QUESTION: 9

**Q. 0.5, 1.5, 4.5, 13.5, (___)**

Solution:

1st term = 0.5

2nd term = 0.5 * 3 = 1.5

3rd term = 1.5 * 3 = 4.5

4th term = 4.5 * 3 = 13.5

**Thus, the missing number is 5th term = 13.5 * 3 = 40.5**

QUESTION: 10

**Q. 19, 2, 38, 3, 114, 4, (____)**

Solution:

The sequence is a combination of two series:

**I.** 19, 38, 114, (____)

**II. **2, 3, 4

Considering Series I:

1st term = 19

2nd term = 19*2 = 38

3rd term = 38*3 = 114

**Thus, the missing number is 4th term = 114 * 4 = 456**

QUESTION: 11

**Q. 1, 2, 3, 6, 9, 18, (___), 54**

Solution:

1st term = 1

2nd term = 1 + (1) = 2

3rd term = 2 + (1) = 3

4th term = 3 + (3) = 6

5th term = 6 + (3) = 9

6th term = 9 + (9) = 18

7th term = 18 + (9) = 27

8th term = 27 + (27) = 54

**Thus, the missing term is 7th term = 27**

QUESTION: 12

**Q. 12, 32, 72, 152, (____)**

Solution:

1st term = 12

2nd term = 12 + 20 = 32

3rd term = 32 + 40 = 72

4th term = 72 + 80 = 152

**Thus, the missing term is 5th term = 152 + 160 = 312**

QUESTION: 13

**Q. 3, 6, 5, 20, 7, 42, 9, (____)**

Solution:

The sequence is a combination of two series:

**I. **3, 5, 7, 9

**II. **6, 20, 42, (____)

Consider II sequence

1st term = 6

2nd term = 6 + 14 = 20

3rd term = 20 + 22 = 42

**Thus, the missing term is 4th term = 42 + 30 = 72**

QUESTION: 14

**Q. 1, 3, 4, 8, 15, 27, (____)**

Solution:

1st term = 1

2nd term = 3

3rd term = 4

4th term = 1 + 3 + 4 = 8

5th term = 3 + 4 + 8 = 15

6th term = 4 + 8 + 15 = 27

**Thus, the missing term is 7th term = 8 + 15 + 27 = 50**

QUESTION: 15

**Q. 95, 115.5, 138, (____), 189**

Solution:

1st term = 95

2nd term = 95 + 20.5 = 115.5

3rd term = 115.5 + 22.5 = 138

4th term = 138 + 24.5 = 162.5

5th term = 162.5 + 26.5 = 189

**Thus, the missing term is 4th term = 162.5**

QUESTION: 16

In this questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the black spaces.

**Q. 24, 60, 120, 210, (____)**

Solution:

1st term = 24

2nd term = 24 + [6 x (6 + 0)] = 60

3rd term = 60 + [6 x (6 + 4)] = 120

4th term = 120 + [6 x (6 + 9)] = 210

**Thus, the missing term is 5th term = 210 + [6 x (6 + 15)] = 210 + 126 = 336**

QUESTION: 17

In this questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the black spaces.

**Q. 34, 18, 10, 6, 4, (___)**

Solution:

1st term = 34/2 +1 = 18

2nd term = 18/2 +1 = 10

3rd term = 10/2 +1 = 6

4th term = 6/2 + 1 = 4

**Thus, the missing number is 5th term = 4/2 + 1 = 3**

QUESTION: 18

In this questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and fill in the black spaces.

**Q. 0.5, 0.55, 0.65, 0.8, (___)**

Solution:

1st term = 0.5

2nd term = 0.5 + 0.05 = 0.55

3rd term = 0.55 + 0.1 = 0.65

4th term = 0.65 + 0.15 = 0.8

**Thus, missing number is 5th term = 0.8 + 0.2 = 1**

QUESTION: 19

**Q. 17, 19, 23, 29, (____),37**
