ANSWERS with explanation
1. The pattern is :
3523 – 3459 = 64 = 43
3459 – 3243 = 216 = 6 3
? = 3243 – 8 3 = 3243 – 512 = 2731
2731 – 1731 = 1000 = 103
1731 – 3 = 1728 = 123
2.  The pattern is :-
10 x 2 – 2 = 20 – 2 = 18
18 x 2 – 2 = 36 – 2 = 34
34 x 2 – 2 = 68 – 2 = 66
66 x 2 – 2 = 132 – 2 = 130
3.  The pattern is :-
4 x 2 + 2 = 10
10 x 3 + 3 = 33
33 x 4 + 4 = 136
136 x 5 + 5 = 680 + 5 = 685
4. The pattern is –
4000 ÷ 5 = 800
800 ÷ 2 = 400
400 ÷ 5 = 80
80 ÷ 2 = 40
40 ÷ 5 = 8
5. The pattern of the number is –
8 + 2 = 10
10 + 8 (= 2 x 3 + 2) = 18
18 + 26 (=3 x 8 + 2) = 44
44 + 80 (=3 x 26 + 2) = 124
124 + 242 (=3 x 80 + 2) = 366
6. The pattern of the number series is –
13 + 1 x 12 = 13 + 12 = 25
25 + 33 x 12 = 25 x 36 = 61
61 + 5 x 12 = 66 x 60 = 121
121 + 7 x 12 = 121 + 84 = 205
205 + 9 x 12 = 205 + 108 = 313
7.  The pattern of the number series is-
656/2 + 24 = 328 + 24 = 352
352/2 + 24 = 176 + 24 = 200
200/2 + 24 = 100 + 24 = 124
124/2 + 24 = 62 + 24 = 86
86/2 + 24 = 43 + 24 = 67
8.  The pattern of the number series is –
454 + 18 = 472
472 – 27 = 445
445 + 18 = 463
463 – 27 = 436
463 + 18 = 454
9. The pattern of the number series is-
12 x 4 – 30 = 48 – 30 = 18
18 x 4 – 36 = 72 – 36 = 36
36 x 4 – 42 = 144 – 42 = 102
102 x 4 – 48 = 408 – 48 = 360
360 x 4 – 54 = 1440 – 54 =1386
10.  The pattern of the number series is –
3 x 1 + 1 3 = 4
4 x 2 + 2 3 = 8 + 8 = 16
16 x 3 + 3 3 = 48 + 27 = 75
75 x 4 + 4 3 = 300 + 64 = 364
364 x 5 + 5 3 = 1820 + 125 = 1945

SHORTCUTS FOR SQUARING

    Squaring of a number whose last digit is 1
    (31)2

    Step1:Write the square of the previous number
    (30)2 = 900
    Step2:Now add the previous number and the number whose square is being asked
    30+31=61
    Step3: Now add Step1 and Step 2
    900+61= 961

    NOTE : If the unit digit of a number is 1 than the unit digit of its square is always 1.
    Squaring of a number whose last digit is 9
    (29)2

    Step1:Write the square of the next number.
    (30)2 =900
    Step2: Now Add the number whose square is being asked and the next number.
    29+30=59
    Step3:Now subtract step1 from step2
    900-59 = 841

    NOTE : If the unit digit of a number is 9 than the unit digit of its square is always 1.
    Squaring of a number whose last digit is 2 or 8
        Use this formula for Squaring of a number whose last digit is 2
        (x-2)2 + 2(x + (x-2)) = a

        Example :(42)2
        (40)2+ 2(42 + 40)= 1600 + 2 X 82
        = 1600 + 164
        = 1764
        Use this formula for Squaring of a number whose last digit is 8
        (x+2)2 – 2(x + (x+2)) = a

        Example : (48)2
        (50)2 – 2(48+50) = 2500 – 2 X 98
        = 2500 – 196
        = 2304

    NOTE : If the unit digit of a number is 2 or 8 than the unit digit of its square is always 4.
    Squaring of a number whose last digit is 5
    (35)2

    Step1:Unit digit is 5 , (5)2= 25
    Step2: Now Add 1 to the ten’s digit and multiply it with the ten’s digit .
    3 X (3+1) = 3 X 4
    = 12
    Step3: Place the step 2 first and step 1 second
    Therefore the answer will be 1225

    NOTE : If the unit digit of a number is 5 than the unit digit of its square is always 5.
    Squaring of a number whose last digit is 3 or 7
        Use this formula for Squaring of a number whose last digit is 3
        (x-3)2 + 3(x + (x-3)) = a

        Example :(43)2
        (40)2+ 3(43 + 40)= 1600 + 3 X 83
        = 1600 + 249
        = 1849
        Use this formula for Squaring of a number whose last digit is 7
        (x+3)2 – 3(x + (x+3)) = a

        Example : (47)2
        (50)2 – 3(47+50) = 2500 – 3 X 97
        = 2500 – 291
        = 2209

    NOTE : If the unit digit of a number is 3 or 7 than the unit digit of its square is always 9.
    Squaring of a number whose last digit is 4 or 6
        Use this formula for Squaring of a number whose last digit is 4
        (x-4)2 + 4(x + (x-4)) = a

        Example :(44)2
        (40)2+ 4(44 + 40)= 1600 + 4 X 84
        = 1600 + 336
        = 1936
        Use this formula for Squaring of a number whose last digit is 6
        (x+4)2 – 4(x + (x+4)) = a

        Example : (46)2
        (50)2 – 4(46 + 50) = 2500 – 4 X 96
        = 2500 – 384
        = 2116

    NOTE : If the unit digit of a number is 4 or 6 than the unit digit of its square is always 6.

ANSWERS with explanation

1. The pattern is :
3523 – 3459 = 64 = 4³
3459 – 3243 = 216 = 6 ³
? = 3243 – 8 ³ = 3243 – 512 = 2731
2731 – 1731 = 1000 = 10³
1731 – 3 = 1728 = 12³

2.  The pattern is :-
10 x 2 – 2 = 20 – 2 = 18
18 x 2 – 2 = 36 – 2 = 34
34 x 2 – 2 = 68 – 2 = 66
66 x 2 – 2 = 132 – 2 = 130

3.  The pattern is :-
4 x 2 + 2 = 10
10 x 3 + 3 = 33
33 x 4 + 4 = 136
136 x 5 + 5 = 680 + 5 = 685

4. The pattern is –
4000 ÷ 5 = 800
800 ÷ 2 = 400
400 ÷ 5 = 80
80 ÷ 2 = 40
40 ÷ 5 = 8

5. The pattern of the number is –
8 + 2 = 10
10 + 8 (= 2 x 3 + 2) = 18
18 + 26 (=3 x 8 + 2) = 44
44 + 80 (=3 x 26 + 2) = 124
124 + 242 (=3 x 80 + 2) = 366

6. The pattern of the number series is –
13 + 1 x 12 = 13 + 12 = 25
25 + 33 x 12 = 25 x 36 = 61
61 + 5 x 12 = 66 x 60 = 121
121 + 7 x 12 = 121 + 84 = 205
205 + 9 x 12 = 205 + 108 = 313

7.  The pattern of the number series is-
656/2 + 24 = 328 + 24 = 352
352/2 + 24 = 176 + 24 = 200
200/2 + 24 = 100 + 24 = 124
124/2 + 24 = 62 + 24 = 86
86/2 + 24 = 43 + 24 = 67

8.  The pattern of the number series is –
454 + 18 = 472
472 – 27 = 445
445 + 18 = 463
463 – 27 = 436
463 + 18 = 454

9. The pattern of the number series is-
12 x 4 – 30 = 48 – 30 = 18
18 x 4 – 36 = 72 – 36 = 36
36 x 4 – 42 = 144 – 42 = 102
102 x 4 – 48 = 408 – 48 = 360
360 x 4 – 54 = 1440 – 54 =1386

10.  The pattern of the number series is –
3 x 1 + 1 ³ = 4
4 x 2 + 2 ³ = 8 + 8 = 16
16 x 3 + 3 ³ = 48 + 27 = 75
75 x 4 + 4 ³ = 300 + 64 = 364
364 x 5 + 5 ³ = 1820 + 125 = 1945
