Number Series (Missing/Wrong Number) Quiz-1

The pattern of the series:
1024 × 0.75 = 768
768 × 0.75 = 576
576 × 0.75 = 432
432 × 0.75 = 324
324 × 0.75 = 243
∴ The wrong number is 625.

The pattern of the series:
56 + 1 = 57
57 + 3 = 60
60 + 5 = 65
65 + 7 = 72
72 + 9 = 81
81 + 11 = 92
∴ The wrong number is = 64.

The pattern of the series:
(- 1)¹ = – 1
(- 2)² = 4
(- 3)³ = – 27
(- 4)⁴ = 256
(- 5)⁵ = – 3125
∴ The wrong number is 216.

The pattern of the series:
12 + 1² = 13
13 + 2² = 17
17 + 3² = 26
26 + 4² = 42
42 + 5² = 67
67 + 6² = 103
103 + 7² = 152
∴ The wrong number is 45

32+2²=32+4=36
36+3³=36+27=63
63+4²=63+16=79
79+5³=79+125=204
204+6²=204+36=240

8, 5, 6, 10, 21, ?
5 = 8*0.5 + 1
6 = 5*1 + 1
10 = 6*1.5 + 1
21 = 10*2 + 1
? = 21*2.5 + 1 = 53.5

27+7=34
34+9=43
43+11=54
54+13=67
67+15=82
82+17=99

The pattern of the series:
1536 – 8³ = 1024
1024 – 7³ = 681
681 – 6³ = 465
465 – 5³ = 340
340 – 4³ = 276
276 – 3³ = 249
∴ The wrong number is 343.

The pattern of the series:
7 + 1³ = 8
8 – 2³ = 0
0 + 3³ = 27
27 – 4³ = – 37
-37 + 5³ = 88
88 – 6³ = – 128
∴ The wrong number is – 3.

Pattern difference is :
+2³−1, +3³−2, +4³−3, +5³−4, +6³−5…………
So answer will be 216+6³−5=427
