Answers:



1. 2
2. 4
3. 3
4. 1
5. 2
6. 1; Here the series is:
14 × 1 – 1 = 13
13 × 2 – 4 = 22
22 × 3 – 9 = 57
57 × 4 – 16 = 212
212 × 5 – 25 = 1035
Hence, the wrong number is 55.
7. 3; Here the series is:
217 + 7 = 224
224 – 11 = 213
213 + 13 = 226
226 – 17 = 209
209 + 19 = 228
Hence, the wrong number is 210.
8. 5; Here the series is:
 153 + 73 = 496
496 + 63 = 712
712 + 53 = 837
837 + 43 = 901
901 + 33 = 928
Hence, the wrong number is 495.
9. 2; Here the series is:
11 × 7 – 7 × 5 = 42
42 × 6 – 6 × 6 = 216
216 × 5 – 5 × 7 = 1045
1045 × 4 – 4 × 8 = 4148
4148 × 3 – 3 × 9 = 12417
Hence, the wrong number is 214.
10. 4; Here, the series is
488 ÷ 2 + 1.0 = 245
245 ÷ 2 + 1.5 = 124
124 ÷ 2 + 2.0 = 64
64 ÷ 2 + 2.5 = 34.5
34.5 ÷ 2 + 3.0 = 20.25

Hence, the wrong number is 35.
