1) 55

2) 13

3) 212

4) 22

5) None of these

Option: 1

Explanation:

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.

1. 217 224 213 226 210 228

1) 213

2) 226

3) 210

4) 228

5) None of these

Option: 3

Explanation:

217 + 7 = 224

224 – 11 = 213

213 + 13 = 226

226 – 17 = 209

209 + 19 = 228

Hence, the wrong number is 210.

1. 153 495 712 837 901 928

1) 712

2) 837

3) 901

4) 928

5) None of these

Option: 5

Explanation:

153 + 73 = 496

496 + 63 = 712

712 + 53 = 837

837 + 43 = 901

901 + 33 = 928

Hence, the wrong number is 495.

1. 11 42 214 1045 4148 12417

1) 42

2) 214

3) 1045

4) 4148

5) None of these

Option: 2

Explanation:

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.

1. 488 245 124 64 35 20.25

1) 124

2) 64

3) 245

4) 35

5) None of these

Option: 4

Explanation:

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.
