Answers :

Directions (1-5) :

1) Answer: b)

1 * 4 = 4

4 * 5 = 20

20 * 6 = 120

120 * 7 = 840

840 * 8 = 6720

2) Answer: a)

(8776 – 8)/8 = 1096

(1096 – 8)/8 = 136

(136 – 8)/8 = 16

(16 – 8)/8 = 1

Hence first term = 8776 * 8 + 8 = 70216

3) Answer: b)

13 + 12 + 13 =15

15 + 22 + 23 = 27

27 + 32 + 33 = 63

63 + 42 + 43= 143

143 + 52 + 53 = 293

4) Answer: c)

5) Answer: d)

6 * 1/2   = 3

3 * 2/2 = 3

3 * 3/2   = 4.5

4.5 * 4/2 = 9

9 * 5/2 = 22.5

6) Answer: c)

So instead of 120 it should be 132.

7) Answer: e)

37 * 2 + 1 = 75

75 * 3 + 2 = 227

227 * 4 + 3 = 911

911 * 5 + 4 = 4559

4559 * 6 + 5 = 27359

8) Answer: a)

107 + 11 = 118

118 + 13 = 131

131 + 17 = 148

148 + 19 = 167

167 + 23 = 190

9) Answer: e)

There are two series in this case. One starts with 17 the other one from 18.

17 * 2 = 34                       18 * 3 = 54

34 * 2 = 68                        54 * 3 = 162

10) Answer: a)

47 + 7 * 1 = 54

54 + 6 * 2 = 66

66 + 5 * 3 = 81

81 + 4 * 4 = 97

97 + 3 * 5 = 112
