Number Series (Logical Reasoning)

This option is right because the given series is based on the following pattern:
750 x 0.75 = 562.5
562.5 x 0.75 = 421.875
421.875 x 0.75 = 316.406
316.406 x 0.75 = 237.304
237.304 x 0.75 = 177.978
? = 177.978 x 0.75 = 133.483
Hence, 133.483 will replace the question mark.

This option is correct because the given series is based on the following pattern:
-28 + 16 = -12
-12 + 32 = 20
20 + 48 = 58
58 + 64 = 122
122 + 80 = 202
202 + 96 = 298
Hence, 298 will replace the question mark.

This is a right option because the given series is based on the following pattern:
(-1)¹ = 1
(-2)² = 4
(-3)³ = -27
(-4)⁴ = 256
(-5)⁵ = -3125
(-6)⁶ = 46656
Therefore, ? = (-7)⁷ = -823543

Hence, - 823543 will replace the question mark.

This option is correct because the given series is based on the following pattern:
6 x 1.5 x 1 = 9
9 x 1.5 x 2 = 27
27 x 1.5 x 3 = 121.5
121.5 x 1.5 x 4 = 729
729 x 1.5 x 5 = 5467.5
? = 5467.5 x 1.5 x 6 = 49207.5
Hence, 49207.5 will replace the question mark.

The given series is based on the following pattern:
17 x 1 + 2 = 19
19 x 2 + 3 = 41
41 x 3 + 4 = 127
127 x 4 + 5 = 513
513 x 5 + 6 = 2571
? = 2571 x 6 + 7 = 15433
Hence, 15433 will replace the question mark.

This option is correct because the given series is based on the following pattern:
280 + 75 = 355
355 + (75 + 1 x 7 = 82) = 437
437 + (75 + 2 x 7 = 89) = 526
526 + (75 + 3 x 7 = 96) = 622
622 + (75 + 4 x 7 = 103) = 725
? = 725 + (75 + 5 x 7 = 110) = 835
Hence, 835 will replace the question mark.

The given series is based on the following pattern:
33 + 2 = 35
35 – 5 = 30
30 + 2 = 32
32 – 5 = 27
27 + 2 = 29
29 – 5 = 24
? = 24 + 2 =26
Hence, 26 will replace the question mark.

This option is correct because the given series is based on the following pattern:
1⁶ = 6
2⁵ = 32
3⁴ = 81
? = 4³ = 64
5² = 25
Hence, 64 will replace the question mark.

The given series is based on the following pattern:
9112.5 ÷ 1.5 = 6075
6075 ÷ 1.5 = 4050
4050 ÷ 1.5 = 2700
2700 ÷ 1.5 = 1800
1800 ÷ 1.5 = 1200
? = 1200 ÷ 1.5 = 800
Hence, 800 will replace the question mark.

This option is correct because the given series is based on the following pattern:
139 + 3 x 21 = 202
202 + 4 x 21 = 286
286 + 5 x 21 = 391
391 + 6 x 21 = 517
517 + 7 x 21 = 664
? = 664 + 8 x 21 = 832
Hence, 832 will replace the question mark.

This option is correct because the given series is based on the following pattern:
6³ = 216
5⁵ = 3125
4³ = 64
3⁵ = 243
2³ = 8
? = 1⁵ = 5
Hence, 5 will replace the question mark.

The given series is based on the following pattern:
10 x 1 + 0 x 1 = 10
10 x 2 + 2 x 2 = 24
24 x 3 + 4 x 3 = 84
84 x 4 + 6 x 4 = 360
360 x 5 + 8 x 5 = 1840
? = 1840 x 6 + 10 x 6 = 11100
Hence, 11100 will replace the question mark.

This option is correct because the given series is based on the following pattern:
15 x 0.25 = 3.75
3.75 x 0.5 = 1.875
1.875 x 0.75 = 1.406
1.406 x 1 = 1.406
1.406 x 1.25 = 1.7575
1.7575 x 1.5 = 2.636
? = 2.636 x 1.75 = 4.613
Hence, 4.613 will replace the question mark.

This option is correct because the given series is based on the following pattern:
27 x 2 – 3 = 54 – 3 = 51
51 x 3 – 2 = 153 – 2 = 151
151 x 2 – 3 = 302 – 3 = 299
299 x 3 – 2 = 895
895 x 2 – 3 = 1787
? = 1787 x 3 – 2 = 5359
Hence, 5359 will replace the question mark.

This option is correct because the given series is based on the following pattern:
7.2 + 8.1 = 15.3
8.1 + 15.3 = 23.4
15.3 + 23.4 = 38.7
23.4 + 38.7 = 62.1
? = 38.7 + 62.1 = 100.8
Hence, 100.8 will replace the question mark.
