A
35

B
36

C
48

D
49

Solution

1st term = 1² = 1
2nd term = 2² = 4
3rd term = 3² = 9
4th term = 4² = 16
5th term = 5² = 25
Thus, Missing number = 6² = 36
Question 2
1 / -0.25

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.

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
1 / -0.25

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.

12

B
13

C
14

D
15

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
1 / -0.25

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

A
42

B
51

C
81

D
91

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
1 / -0.25

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

A
324

B
210

C
243

D
162

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
1 / -0.25

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, 5, 9, (___), 20, 27

A
16

B
14

C
18

D
24

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
1 / -0.25

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

A
65

B
60

C
70

D
68

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

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
1 / -0.25

39.5

D
40.5

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
1 / -0.25

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.

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
