3,1.5,1,0.75,0.6,( ),( ),( )规律是什么
3,1.5,1,0.75,0.6,( ),( ),( )规律是什么

3,1.5,1,0.75,0.6,( ),( ),( )规律是什么
3×1/2=1.5
1.5×2/3=1
1×3/4=0.75
0.75×4/5=0.6
()=0.6×5/6=0.5
()=0.5×6/7=3/7
()=(3/7)×(7/8)=3/8
3,1.5,1,0.75,0.6,( 0.5),(3/7 ),(3/8 )
规律:从第二项开始,依次为前一项乘以(项数-1)/项数.

乘1/2乘2/3乘3/4乘4/5乘等

依次乘以1/2,2/3,3/4,4/5,……
3,1.5,1,0.75,0.6,( 0.5),( 3/7),(3/8 )。

3/1.3/2.3/3.3/4.3/5
看懂了么。第一个是1分之3,第二个是2分之3,所以第n个是n分之3
所以第六个是3/6
第七个3/7
第八个3/8

3×1/2=1.5
1.5×2/3=1
1×3/4=0.75
0.75×4/5=0.6
()=0.6×5/6=0.5
()=0.5×6/7=3/7
()=(3/7)×(7/8)=3/8
3,1.5,1,0.75,0.6,( 0.5),(3/7 ),(3/8 )
规律:从第二项开始,依次为前一项乘以(项数-1)/项数
