2009年7月1日 · 2 5 5 10 加减乘除都可以怎样算成24有几种方式没有其它的算法了!下面是从专门算24点的网站下载的算法,其实都是一种算法!1: (5 - 2 ÷ 10) × 52: (5 - (2 ÷ 10)) × 53: 5 × (5 - 2 ÷ 10)4: 5 × (5 - (2 ÷

以此类推，1 2 5 10 17 26 37……还可以看成是0^2+1、1^2+1、2^2+1、3^+1、4^2+1……37后面是7^2+1=50。 两种方法都可以理解.1^2表示1的平方。

2012年6月23日 · 第一种----等差数列：是指相邻之间的差值相等，整个数字序列依次递增或递减的一组数。 1、等差数列的常规公式。 设等差数列的首项为a1，公差为d ，则等差数列的通项公式为an=a1+ (n-1)d (n为自然数)。 [解析] 这是一种很简单的排列方式：其特征是相邻两个数字之间的差是一个常数。 从该题中我们很容易发现相邻两个数字的差均为2，所以括号内的数字应为11。 故选C。 2、二级等差数列。 是指等差数列的变式，相邻两项之差之间有着明显的规律性,往往构成 …
