1. 36
2. 33
3. 39
4. 43
5. 31

Solution:

The pattern of the series is:

3 + 4 = 7

7 + 8 = 15

15 + 16 = 31

31 + 32 = 63

63 + 64 = 127

Q7) 7 , 6 , 8 , 15 , 44 , ?

1. 185
2. 187
3. 192
4. 195
5. 198

Solution: 

Pattern of the series is:
7 × 1 − 1² = 6

6 × 2 − 2² = 8

8 × 3 − 3² = 15

15 × 4 − 4² = 44

44 × 5 − 5² = 195

Q8) 17, 19, 33, ?, 129, 227

1. 64
2. 73
3. 67
4. 72
5. None of these

Solution: 

The pattern of the series is:

17 + (2² – 2) = 19
19 + (4² – 2) = 33
33 + (6² – 2) = 67
67 + (8² – 2) = 129
129 + (10² – 2) = 227

So the missing no. is 67.
