只答对第三题与第八题。其它都不对 www.ddhw.com     本贴由[开开心心]最后编辑于：2007-12-30 10:9:39

  严重怀疑你的标答 在你公布标答后让我们比较一下什么是最合理的答案.

开开心心

为什么不合理？我只知道答案是唯一，其它就不知道 www.ddhw.com

husonghu

不管你有否过程解释, 你可以给出(与我不同的)某一题的标答, 比如就第一题吧! 让我们看看到底谁对谁错. 如果你(你公司)拿不出理由, 那我就把我的拿出来给大家看 www.ddhw.com

Question 4: 1,5,17,48,109,211,365,?   先依次后项减前项得一序列:    4,12,31,61,102,154,? 尚看不清楚,再依次后项减前项得一序列: 8,19,30,41,52,? 其实到这里就可看出规律了: 相邻项递增11. 要不然, 再来一次, 再依次后项减前项得一序列: 11,11,11,11,? 倒推回去: 11后还是11 ---> 52后是63 ---> 154后是217 ---> 故365后是(答案)582     Question 10: 1,6,12,21,42,123,564,?   先依次后项减前项得一序列: 5,6,9,21,81,441,? 再依次后项减前项得一序列: 1,3,12,60,360,?www.ddhw.com 可看出,此序列是这样构成的: 第一项乘3得第二项, 第二项乘4得第三项, 第三项乘5得第四项, 第四项乘6得第五项,... 所以, 倒推回去: 360后是360X7=2520 ---> 441后是2961 ---> 564后是(答案)3525   (其它几题也是类似的思路) www.ddhw.com

因为每题要附上算式才会计算积分，只做选择一律当错   令husonghu兄受惊，抱歉的说。   我並沒有走开，1号不用上班，你的问题无从作答而已   这回husonghu兄就答对 www.ddhw.com
