18 16 14 12

4,12

4,12

1,18,2,16,3,14,( 4 ),(12 )
隔一个数看规律。

4 12

4 和 12

1,18,2,16,3,14,(4 ),(12 )

1,18,2,16,3,14,(4 ),(12 )
显然奇数项是1.2.3……的自然数序列
而偶数项是以18为首项公差为2的等差递减数列
希望可以帮助到你

1,18,2,16,3,14,4,12

(1)第一组数:1,2,3,(4)
(2)第二组数:18,16,14,(12)
括号里填4和12

1,18,2,16,3,14,(4),(12)

1 18 2 16 3 14 (4) (12)

4 12

1,18,2,16,3,14,(4 ),(12 )

4和12

1,18,2,3,14,4,12

1 18 2 16 3 14 (4) (12)...........(5 10) (6 8) (7 6) (8 4) (9 2)
可以这么理解
1 2 3 4 5 6 7 8 9
18 /2=9 16/2=8 14/2=7 6 5 4 3 2 1
