C
121

D
100

E
80

Solution

Numbers must be $$(14)^2, (13)^2, (12)^2, (11)^2, (10)^2, (9)^2, (8)^2$$.
So, 80 is wrong.
Question 2

Solution

Go on adding 7, 9, 11, 13, 15, 17 respectively to obtain the next number.
So, 33 is wrong. It must be 35
Question 3

36, 54, 18, 27, 9, 18.5, 4.5

A
4.5

B
18.5

C
54

D
18

Solution

The terms are alternatively multiplied by 1.5 and divided by 3. However, 18.5 does not satisfy it.
Question 4
1 / -0

25, 36, 49, 81, 121, 169, 225

A
36

B
49

C
121

D
169

Solution

The numbers are squares of odd natural numbers, starting from 5 up to 15.
So, 36 is wrong.
Question 5
1 / -0

1, 1, 2, 6, 24, 96, 720

A
720

B
96

C
24

D
6

E
2

Solution

Go on multiplying with 1, 2, 3, 4, 5, 6 to get next number.
So, 96 is wrong.
Question 6
1 / -0

190, 166, 145, 128, 112, 100, 91

A
100

B
166

C
145

D
128

E
112

Solution

Go on subtracting 24, 21, 18, 15, 12, 9 from the numbers to get the next number.
190 - 24 = 166
166 - 21 = 145
145 - 18 = 127 [Here, 128 is placed instead of 127]
127 - 15 = 112
112 - 12 = 100 ... and so on.
Therefore, 128 is wrong.
Question 7
1 / -0

46080, 3840, 384, 48, 24, 2, 1

A
1

B
2

C
24

D
384

Solution

The terms are successively divided by 12, 10, 8, 6, ...etc.
So, 24 is wrong, it should be 8 (48/6 = 8).
Question 8
1 / -0

56, 72, 90, 110, 132, 150

A
72

B
110

C
132

D
150

Solution

The numbers are 7 x 8, 8 x 9, 9 x 10, 10 x 11, 11 x 12, 12 x 13.
So, 150 is wrong.
Question 9
1 / -0

7, 8, 18, 57, 228, 1165, 6996

A
8

B
18

C
57

D
228

E
1165

Solution

Let the given numbers be A, B, C, D, E, F, G.
Then, A, A x 1 + 1, B x 2 + 2, C x 3 + 3, D x 4 + 4, E x 5 + 5, F x 6 + 6 are the required numbers.
Clearly, 228 is wrong.
Question 10
1 / -0

6, 12, 48, 100, 384, 768, 3072

A
768

B
384

C
100

D
48

E
12

Solution

Each even term of the series is obtained by multiplying the previous term by 2.
2nd term = (1st term) x 2 = 6 x 2 = 12
4th term = (3rd term) x 2 = 48 x 2 = 96.
6th term = (5th term) x 2 = 384 x 2 =768.
4th term should be 96 instead of 100.
