在一次抽样调查中收集了一些数据，对数据进行分组，绘制了频数分布表，由于操作失误，绘制时不慎把第三小组的频数弄丢了，现在只知道最后一组（89.5～99.5）出现的百分比为15%，由此可知丢失的第三小组的频数是____。

古诗文默写。
①                ，江春入旧年。         （王湾《次北固山下》）
②塞下秋来风景异，           。    （范仲淹《渔家傲•秋思》）
③           ，吟鞭东指即天涯。       （龚自珍《己亥杂诗》）
④政通人和，                 。        （范仲淹《岳阳楼记》）
⑤      ，      。     ，     。（李商隐《夜雨寄北》）
⑥《白雪歌送武判官归京》中的“           ，           ”虽只字未提送别，笔端却饱含悠悠不尽之情思，达到了“此时无声胜有声”的艺术效果。
