一年级就学这么难吗?
(9) (8.5 ) (8) (7.5) (7) (6.5) ( 6 ) (5.5) ( 5) ( 4.5) ( 4) ( 3.5) ( 3) ( 2.5) ( 2) (1.5) (1) (0.5)

收起

(9)(1)(8)(2)(7)(3)6(4)5(5)(4)(6)3(7 )(2)(8 )(1)(9)

每个数乘2就是后面的数 如下: 8*2=16 16*2=32 32*2=64 64*2=12816,32,64,128,256,512,1024,2048,4096,8192……规律是后一个数

9 8.5 8 7.5 7 6.5 6 5.5 5 4.5 4 3.5 3 2.5 2 1.5 1 0.5

9 9 8 8 7 7 6 6 5 5 4 4 3 3 2 2 1 1

现在小学生的题都这难啊,真不容易啊
(9) (1) (8) (2)(7)(3)(6)(4)(5)(5)(4)(6)(3)(7 )(2)(8 )(1)(9)
