1)The series is,
6 ×1 + 7×1 = 13
13× 2+ 6×2 = 38
38× 3+ 5×3 = 129
129 × 4 + 4×4 = 532
532 × 5 + 3×5 = 2675.
2.15, 17, 24, 45, ?, 381
56
68
121
116

2).The series is,
15+12+1 = 17
17+22+3 = 24
24+42+5 = 45
45+82+7 = 116
116+162+9 = 381.

3).The series is,
4×1 + 2 = 6
6×1.5 + 4 = 13
13×2 + 6 = 32
32×2.5 + 8 = 88
88×3 + 10 = 274
274×3.5 + 12 = 971.

1992
1921
1975
1918
1945
5).The series is,
6222 - (74-7) = 6222 – (2401-7) = 3828
3828 - (64-6) = 3828 – (1296-6) =2538
2538 - (54-5) = 2538 – (625-5) = 1918
1918 - (44-4) =1918 – (256-4) = 1666
1666 - (34-3) = 1666 – (81-3) = 1588

Direction (Q. 6-10): In each of these questions a number series is given. In each series only one number is wrong. Find out the wrong number.
6.32, 39, 65, 128, 253, 467, 809, 1320
39
65
253
467
32
6).The series is,.

Hence, 253 is a wrong number.

7.38, 49, 62, 72, 77, 91, 101
49
72
77
91
38
7).The series is,
38 = 3+8 = 11 = 38 +11 = 49
49 = 4+9 = 13 = 49 +13 = 62
62 = 6+2 = 8 = 62 + 8 = 70 ≠ 72
70 = 7+0 = 7 = 70+ 7 = 77
77 = 7+7 = 14 = 77+14 = 91
91 = 9+1 = 10 = 91+10 = 101
Hence, 72 is the wrong number.
8.19, 22, 32, 46, 73, 108, 158
22
46
73
19
158
8).The series is,

Hence, 46 is the wrong number
9.47, 44, 45, 46, 33, 57, 3, 88
44
57
46
3
47
9).First series 47, 45, 33, 3
47-(1×2) = 45
45-(3×4) = 33
33- (5×6) = 3
Second series 44, 46, 57, 88
44 + (1×2) = 46
46 + (3×4) = 58 ≠ 57
58 + (5×6) = 88
Hence, 57 is the wrong answer.
