找规律:2,1,( ),0.25,0.125,( ),0.3125
2,1,( 0.5),0.25,0.125,(0.0625 ),0.3125

2,1,( 0.5),0.25,0.125,(0.0625 ),0.03125
公比为2的等比数列,即前一项除以2等于后一项。
最后一项应该是0.03125

从第一个数向后不断÷2
所以1后面是0.5 0.125后面是0.0625

2,1,(0.5 ),0.25,0.125,( ),0.3125
前一个数除以2得到后一个数 希望能帮到你

2,1,( 0.5),0.25,0.125,(0.0625 ),0.3125
后一个数是前一个数的2分之一

汗,这个都不会!2,1,( 0.5),0.25,0.125,(0.0625 ),0.03125
