1. 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.
2. 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.
3. 5; Here the series is:
153 + 7^3 = 496
496 + 6^3 ? 712
712 +5^3 ? 837
837 + 4^3 ? 901
901+ 3^3 ? 928
Hence, the wrong number is 495.
4. 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.
5. 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
