私がする必要があるのは、1 番目 5 番目 9 番目 13 番目の div などにクラスを追加することですが、私が書いたスクリプトはハードコードされており、問題なく動作しますが、問題は 5 番目の div のみにクラスを追加することですが、1、5 が必要です。 9など

ここにスクリプトがあります：

           $('div.impresna-wrapp').find('div.impresna:nth-child(5)').each(function() {
           $(this).addClass("alter-impresna");
            });
