The pattern is :
190 – 24 = 166
166 – 21 = 145
145 – 18 = 127 ≠ 128
........... and so on.

Correct Option: D

The pattern is :
190 – 24 = 166
166 – 21 = 145
145 – 18 = 127 ≠ 128
Since , 128 is wrong term . so , 127 is correct term .
127 – 15 = 112
112 – 12 = 100
100 – 9 = 91
Thus , wrong number in the series is 128.

The pattern is :
40960 ÷ 4 = 10240
10240 ÷ 4 = 2560
2560 ÷ 4 = 640
640 ÷ 4 = 160 ≠ 200

Correct Option: B

The pattern is :
40960 ÷ 4 = 10240
10240 ÷ 4 = 2560
2560 ÷ 4 = 640
640 ÷ 4 = 160 ≠ 200
Since , 200 is wrong number . so , 160 is correct number .
160 ÷ 4 = 40
40 ÷ 4 = 10
Thus , required answer is 200.

The pattern is :
3 + 2 = 5
5 + 2 × 2 = 5 + 4 = 9
9 + 2 × 4 = 9 + 8 = 17
17 + 2 × 8 = 17 + 16 = 33
33 + 2 × 16 = 33 + 32 = ?

Correct Option: A

The pattern is :
3 + 2 = 5
5 + 2 × 2 = 5 + 4 = 9
9 + 2 × 4 = 9 + 8 = 17
17 + 2 × 8 = 17 + 16 = 33
33 + 2 × 16 = 33 + 32 = ?
∴ ? = 65
Thus , The next number of the sequence is 65 .
