这道题好山寨啊,哪里搞的版本.还有单词错误.serious肯定错的,该是series,表示一系列啊.看我将其正题吧.原题应该是这样的.There are a series of numbers:1,3,9,25,69,189,517...If the total of the first 2008 figures is divided by 6,what's the result?译成汉语就是有一个数列1,3,9,25,69,189,517...,如果把前2008数加起来然后除以6,结果是多少?解题思路吗,我想楼主现在应该知道了吧?肯定是找规律,从这些数字里提出一个公式,最后应该是一个3或者6的倍数,然后算算差不多就得到结果了.至于这是个什么数列,公式是什么,就需要你自己推算咯.俺也只能帮到这里了.祝你好运啊.
题目看不懂,不过(1+3)乘以2加1得9,3+9乘以2加1得25,9+25乘以2加1得25。。。。以此类推
