An=(n-1)*A(n-1)

1,1,2,6,24,( )。
【答案】:C 多级数列。两两做商为1,2,3,4,故( )=24×5=120,所以选择C选项。

1 1 2 624点怎么算?
1,1,2,6算24 (1+1+2)×6=24

1、2、6、24、后面是什么
回答:1X2=2 2X3=6 6X4=24 24X5=120 120X6=720

1、1丶2丶6丶24()按规律填数是多少?
这个数列中的每一个数都是前一个数乘以一个牢固的数获得的。详细地,第一个数是1,第二个数是1×2=2,第三个数是2×3=6,第四个数是6×4=24,因而第五个数该当是24×5=120。因而,这个数列中按纪律填数的谜底是120。

1,1,2,6,24,( ) A.48 B.96 C.120 D.144
选择C 因为:2=(1+1)*1 6=(1+2)*2 24=(2+6)*3 120=(6+24)*4 故,选C

1,2,6,24的通项公式
1=1 2=1*2 6=1*2*3 24=1*2*3*4 an=n!=1*2*3*……*n

1, 2, 6, 24, ()。
【答案】:B 做商后为等差数列。突破点在24,因为24正好是6的4倍。解法如下:做商得2,3,4,是一个等差数列,接下来的数字是5,所以答案为24×5=120,故应选8。

数字推理1,1,2,6,24,( ) 怎么算啊?
1\/1=1 2\/1=2 6\/2=3 24\/6=4 ()\/24=5 所以说()里面的数就是120了...

1,1,2,6,24有什么规律
这组数1,1,2,6,24的规律可以从不同的角度来观察。以下是一些可能的规律:乘法运算:第一个数1是1的0次方,第二个数1是2的0次方,第三个数2是2的1次方,第四个数6是2的2次方乘以3,第五个数24是2的3次方乘以3。由此可以看出,这组数可以看作是2的幂次方与3的乘积。递推数列:从第...

1,1,2,6,24有什么规律
第一个数乘以1得第二个数,第二个数乘以2得第三个数,第三个数乘以3得第四个数,第四个数乘以4得第五个数。
