A
1、化简得:4/1,12/8,20/27,28/64,36/125
分子等差为8,分母为等差数列的立方
?=34/216
2、9,4,7,-4,5,4,3,-4,,1,4,( ),( )
分奇偶项:9,7,5,3,1
4,-4,4,-4,,4
?=-1,-4
4、化简得:4/6,5/10,6/14,7/18
分子分母均为等差数列
全部展开
1、化简得:4/1,12/8,20/27,28/64,36/125
分子等差为8,分母为等差数列的立方
?=34/216
2、9,4,7,-4,5,4,3,-4,,1,4,( ),( )
分奇偶项:9,7,5,3,1
4,-4,4,-4,,4
?=-1,-4
4、化简得:4/6,5/10,6/14,7/18
分子分母均为等差数列
?=8/22=4/11
5、16,18,21,26,33
后项-前项得:2,3,5,7质数数列
?=33+11=44
6、从第三项起,后项=中项*2+前项
?=41*2+17=99
太多了,就做这么多吧,下面的方法类似
