Wrong Number Series:
59, 41, 68, 33, 77, 23
Therefore, wrong no. is 33
The solution is:
(9 + 1) * 0.5 = 5
(5 + 1) * 1 = 6
(6 + 1) * 1.5 = 10.5
(10.5 + 1) * 2 = 23
(23 + 1) * 2.5 = 60 ≠ 90
(60 + 1) * 3 = 183
Therefore, wrong no. is 90.
The solution is:
(3 + 1) * 2 = 8
(8 + 1) * 2 = 18
(18 + 1) * 2 = 38
(38 + 1) * 2 = 78
(78 + 1) * 2 = 158 ≠ 168
(158 + 1) * 2 = 318
Therefore, wrong no. is 168
The solution is:
3 * 2 + 2 = 8
8 * 2 + 2 = 18
18 * 2 + 2 = 38
38 * 2 + 2 = 78 ≠ 80
78 * 2 + 2 = 158
158 * 2 + 2 = 318
Therefore, wrong no. is 80
(11)*11 – 1 = 120
11*13 = 143
13*131 = 168
13*15 = 195
15*151=225
15*17=255
Answer is 255 so, none of these.
Therefore, wrong no. is 253
Therefore, it must be 42+14 = 56 i.e. 127+56 = 183
56+ 15 = 71 i.e. 183+ 71 = 254
Hence, wrong no. is 185
The solution is :
7 * 1 + 2 = 9
9 * 2 + 3 = 21
21 * 3 + 4 = 67
67 * 4 + 5 = 273 ≠ 275
273 * 5 + 6 = 1371
1371 * 6 + 7 = 8233
Therefore, wrong no. is 275
The solution is :
3 * 2 = 6
6 * 2.5 = 15
15 * 3 = 45
45 * 3.5 = 157.5 ≠ 157
157.5 * 4 = 630
630 * 4.5 = 2835
Therefore, wrong no. is 157
Because, difference of the difference is prime numbers in increasing order . therefore, wrong no. is 131
Therefore, wrong no. is 4
2478/3 – 7 = 819
819/3 – 6 = 267 ≠ 257
267/3 – 5 = 84
84/3 – 4 = 24
24/3 – 3 = 5
Therefore, the wrong no. is 257
The solution is :
(1)3 + 2 = 3
(2)3 + 3 = 11
(3)3 + 4 = 31 ≠ 34
(4)3 + 5 = 69
(5)3 + 6 = 131
Therefore, the wrong no. is 34
The solution is :
9 * .5 + .5 = 5
5 * 1.5 + 1.5 = 9
9 * 2.5 + 2.5 = 25
25 * 3.5 + 3.5 = 91 ≠ 95
91 * 4.5 + 4.5 = 414
Therefore wrong no. is 95
Therefore, wrong no. is 64
Therefore, wrong no. is 57
The solution is :
1 * 9 – 1 = 8
8 * 8 + 2 = 66
66 * 7  3 =459 ≠ 460
459 * 6 + 4 = 2758
2758 * 5 – 5 = 13785
13785 * 4 + 6 = 55146
Therefore, wrong no. is 460
The solution is :
3 * 2.5 = 7.5
15 * 2.5 = 37.5
75 * 2.5 = 187.5 ≠ 167.5
7.5 * 2 = 15
37.5 * 2 = 75
187.5 * 2 = 375
Therefore, wrong no. is 167.5
The solution is:
4 * 2 + (2)2 = 12
12 * 3 + (3)2 = 45 ≠ 42
45 * 4 + (4)2 = 196
196 * 5 + (5)2 = 1005
1005 * 6 + (6)2 = 6066
6066 * 7 +(7)2 = 2511
Therefore, wrong no. is 42
The solution is :
9 * 1 – 1 = 8 ≠ 7
8 * 2 – 1 = 15
15 * 3 – 1 = 44
44 * 4 – 1 = 175
175 * 5 – 1 = 874
Therefore, wrong no. is 7
