将正偶数按下表排成5列：
第1列 第2列 第3列 第4列 第5列
第1行```````````````2````````4````````6`````````8
第2行`````16````````14```````12```````10````````
第3行```````````````18```````20```````22````````24
…```````…````````30```````28```````26````````
----------------------------------------------------
根据上面排列规律：
（1）、第2004应在什么位置？
（2）、第2004行第3列应是多少？
主要是老师们教我怎么分析啊！Thank you very much .
上面的表有点排乱了！！
``````````第1列```第2列```第3列```第4列```第5列

可以把2行作为一组，共8个数，即第一行第一个数与第三行第一个数相差16
1）2004在第251行第2个数
2004/2＝1002个
1002/8＝125组……2
125*2＝250行
即2004应在第251行第2个数
2）第2004行第3列应是16030
2004/2＝1002组
1002*8＝8016个
8016*2-2＝16030
