 43
 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 , ?

 195
 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
 64
 73
 67
 72
 None of these
Solution:
The pattern of the series is:
17 + (2^{2} – 2) = 19
19 + (4^{2} – 2) = 33
33 + (6^{2} – 2) = 67
67 + (8^{2} – 2) = 129
129 + (10^{2} – 2) = 227
So the missing no. is 67.
