(7-1) x 2 = 12
(12 – 2) x 4 = 40
(40 – 3) x 6 = 222
(222 – 4) x 8 = 1744 ≠ 1742
(1744 – 5) x 10 = 17390
(17390 – 6) x 12 = 208608

6 x 7 + 72 = 91 , 91 x 6 + 62 = 582 ≠ 584 , 582 x 5 + 52 = 2935,…

Number of selected employees for finance managers by company B = 200

Number of selected employees for finance managers by company A = 150

Percent = $\frac{200 – 150}{150}$ x 100 = 33.33%

11 = 1 , 22 = 4 , 33 = 27 ≠ 25 , 44 = 256 , 55 = 3125 , 66 = 46656 , 77 = 823543

$\frac{8424}{2}$ = 4212

$\frac{4212}{2}$ = 2106

$\frac{2106}{2}$ = 1053 ≠ 1051

$\frac{1051}{2}$ = 526.5

$\frac{525.5}{2}$ = 263.25

$\frac{263.25}{2}$ = 131.625

5531 – 5= 5506
5506 – 9= 5425
5425 – 112 = 5304
5134 – 132 = 5135
5135 – 15= 4910
4910 – 172 = 4621

Ever number after 5531 has a difference of a square.
Hence 5531 is the wrong number.

This should be the series.

6 + 1 = 7
7 + 2 = 9
9 + 4 = 13
13 + 8= 21
21 + 16 = 37
37 + 32 = 69
Hence, we can say that 26 is incorrect.

(1 x 1) + 2 = 3
(3 x 2) + 4 = 10
(10 x 3) + 6 = 36
(36 x 4) + 8 = 152
(152 x 5) + 10 = 770 ≠760
(770 x 6) + 12 = 4632

02 + 4 = 4
12 + 2 = 3
32 + 0 = 9
62 – 2 = 34
102 – 4 = 96
15– 6 = 219
212 – 8 = 433 ≠ 435

157.5 ÷ 3.5 = 45
45 ÷ 3 = 15
15 ÷ 2.5 = 6
6 ÷ 2 = 3
3 ÷ 1.5 = 2
2 ÷ 1 = 2 ≠ 1

4 = 1*2+2 ; 15 = 4*3+3 ; 64 = 15*4+4 ; 325 = 64*5+5 ; 1956 = 325*6+6

The nth term is of the form,

$T_n=(T_{n-1}\times n)+n$

The last term does not follow the pattern and is thus the wrong number in the sequence.

2*2+2 = 6 ; 3*3+3 = 12 ; 4*4 + 5= 21 ; 5*5 +8 = 33 ; 6*6 + 12 = 48

1.5*2 + 3 = 6

2.5*3 + 4 = 11.5

3.5*4 + 5 = 19

4.5*5 + 6 = 28.5

5.5*6 + 7 = 40

1*2+3=5 ; 4*5+6 = 26 ; 8*9+10 = 82 ; 13*14+15 = 212 ; 19*20 + 21 =401 ; 26*27 +28 = 702

1^2 + 4= 5 ; 2^2 + 16 = 20 ; 3^2 + 64 = 73 ; 4^2 + 256 = 272 ; 5^2 + 1024 = 1049

$4^2 = 16$ ; $5^2=25$ ; $6^2 = 36$ ; $7^2=49$ ; $8^2 = 64$ ; $9^2 = 81$

$1^3 = 1$ ; $3^3 = 27$ ; $5^3 = 125$ ; $7^3=343$ ; $9^3 = 729$

$1 \times11 = 11$ ; $2 \times 22=44$ ; $3 \times 33=99$ ; $4 \times 44=176$ ; $5 \times 55=275$
$1^2 + 2^2 = 5$; $3^2 + 4^2 = 25$ ; $5^2 +6^2 = 61$ , $7^2 + 8^2 = 113$ ; $9^2 + 10^2 = 181$
