7*4+5 = 28+5 = 33
33*4+5 = 132+5 = 137
137*4+5 = 548+5 = 553
553*4+5 = 2212+5 = 2217
2217*4+5 = 8868+5 = 8873
Hence, 8871 must be replaced by 8873

2*3 = 6
3*4 = 12
Next term would be 4*5 = 20
5*6 = 30
6*7 = 42
7*8 = 56
Hence, 15 must be replaced by 20.

The pattern being followed here is *3+1
6*3+1 = 19,
19*3+1=58,
so next term would be 58*3+1= 175
175*3+1 = 526.
Hence, 172 must be replaced by 175.

36 = 6*6
180 = 36*5
720 = 180*4
2160 = 720*3
So the next term will be, 2160*2 = 4320
Hence, 4230 must be replaced by 4320.

$343 = 7^3$
$512 = 8^3$
$729 = 9^3$
$1000 = 10^3$
Here, all numbers are cubes of 7,8,9,10,11,…
Hence, Next number should be $1331 = 11^3$
Hence, 1329 should be replaced by 1331.

$1 = 1^2$
$9 = 3^2$
$25 = 5^2$
$49 = 7^2$
$81 = 9^2$
$121 = 11^2$
Here, Numbers are squares of odd numbers.
Hence, 23 should be replaced by 25.

51+3 = 54
54+5 = 59
59+8 = 67
67+8 = 75
75+11 = 86
Here, Difference between the numbers are odd numbers.
Hence, 67 should be replaced by 66.

21+1 = 22
22+4 = 26
26+9 = 35
35+16 = 51
51+25 = 76
Hence, 74 should be replaced by 76.

$1 = 1^1$
$36 = 6^2$
$121 = 11^2$
$256 = 16^2$
$484 = 22^2$
$676 = 26^2$
Here, Numbers are the squares of 1, 6, 11, 16, 22, 26,…
Difference between these numbers is 5 in all numbers except 16,22,26
Hence, 22 should be replaced by 21 and therefore 484 should be replaced by 441.

784/2 = 392
400/2 = 200
208/2 = 104.
Hence, 102 should be replaced by 104.

The given series is as below
3*1+1 = 3+1 = 4
4*2+4 = 8+4 = 12
12*3+9 = 36+9 = 45
45*4+16 = 180+16 = 196
196*5+25 = 980+25 = 1005

Hence, 12 should be replaced by 10.

11+5 = 16
16+15 = 31
31+25 = 56
56+37 = 93
93+43 = 136
136+55 = 191.
Here, Difference between the numbers are 5, 15, 25, 35, …..
Hence, After 56, it should be
56+35 = 91.
Hence, 93 should be replaced by 91.

5+3 = 8
8+5 = 13
13+2 = 15
15+14 = 29
29+11 = 40
Here, The difference are odd numbers.
Hence, After 13, it should be
13+7 = 20
20+9 = 29.
Hence, 15 should be replaced by 20.

2*2 = 4
4*4 = 16
16*6 = 96
96*8 = 768
768*10 = 7680
Hence, 7860 should be replaced by 7680.

Difference in series is in increasing order as 16,18,20,22,24,….
835-16 = 819
819-18 = 801
801-20 = 781
781-22 = 759
759-24 = 735

Hence, 799 should be replaced by 801.

$3\times1^3 = 3$
$3\times2^3 = 3\times8 = 24$
$3\times3^3 = 3\times27 = 81$
$3\times4^3 = 3\times64 = 192$
$3\times5^3 = 3\times125 = 375$
Hence, 373 must be replaced by 375.

The given series is a combination of two series.
198, 200, 202, …
200, 197, 196,….
In the first series,
198+2 = 200
200+2 = 202
In the second series,
200-3 = 197
197-3 = 194
Hence, 196 must be replaced by 194.

The given series is in the form of
200+19 = 219
219+38 = 257
257+57 = 314
314+76 = 390
Hence, 255 should be replaced by 257.

26+11 = 37
37+13 = 50
50+15 = 65
65+17 = 82
82+19 = 101
Hence, 102 should be replaced by 101.
