Fill in the blanks 1, 1 / 4, 1 / 9, (), (), 1 / 36

1,1/4,1/9,（1/16),(1/25),1/36
The nth number is (1 / N?)

Find the rule and fill in the blank: 1 / 4 1 / 9 1 / 16 () ()

1/25,1/36

Fill in the blanks 1 / 4, - 4,4 / 9, - 9 / 4,9 / 16, (), (), ()

-19 / 9, 16 / 25, 25 / 16

Find patterns 1. - 4.9. - 16.25. - 36

1=1^2
4=2^2
9=3^2
……
So the 2n number -- even
Is - 4N ^ 2
The 2n + 1 number -- odd number
Is (2n + 1) ^ 2

Fill in the blanks 4,9,16,25, () 49,64

The square of (1 + 1) is 4, (2 + 1) is 9, (3 + 1) is 16, (4 + 1) is 25, (5 + 1) is 36, (6 + 1) is 49, and (7 + 1) is 64

Find the rule of 3 / 4,1,4,16 () ()

1=(4/3)*(3/4)
3/4=1*(3/4)
9/16=(3/4)*(3/4)
So:
(9/16)*(3/4)=27/64
(27/64)*(3/4)=81/256

Find the law: 1 / 4-4 / 9 - 9 / 46 () () ()

1 / 4 - 9 / 46 (- 16 / 25) (25 / 36) (- 36 / 49)

Find the rule of 27 / 16, 9 / 16, 3 / 16, (), 1 / 48, () Please hurry up

27 / 16, 9 / 16, 3 / 16, (1 / 16), 1 / 48 (1 / 144)
27 of 16 △ 3 = 9 of 16
9 / 16 / 3 = 3 / 16
3 / 16 △ 3 = 1 / 16
1 / 16 / 3 = 1 / 48
1 / 48 △ 3 = 1 / 14

Find the law: 16 / 9, 8 / 3, 4 / 6, 6 (), ()

16 / 9, 8 / 3, 4 / 6 (9) and (27 / 2)
The latter number is equal to three-thirds of the former
