A
27

B
18

C
36

D
81

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 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.

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

A
312

B
325

C

D
613

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 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.

54

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 + 14 = 34

Thus, the missing term is 4th term = 34 + 14 = 48
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. 1, 3, 4, 8, 15, 27, (____)

A
37

B
44

C
50

D
55

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

A
162.5

B
154.5

C
164.5

D
166.5

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

A
336

B
330
