(2)数列中蕴含的函数思想是研究数列的指导思想,应及早引导学生发现数列与函数的关系.在教学中强调数列的项是按一定顺序排列的,“次序”便是函数的自变量,相同的。下面小编给大家分享数列，希望能帮助到大家。 数列文档下载网址链接：</div></div><div class=\"download_card_btn download_card_btn_lb\"><div class=\"content_box_tj\"><span>推荐度：</span><img src=\"/skin/zhann/images/icon_star.png\" alt=\"\">	<img src=\"/skin/zhann/images/icon_star.png\" alt=\"\">	<img src=\"/skin/zhann/images/icon_star.png\" alt=\"\">	<img src=\"/skin/zhann/images/icon_star.png\" alt=\"\"></div><div class=\"downlod_btn_right demo_tc downlod_btn_right_lb\"><em class=\"downlod_icon\"></em>点击下载文档<span>文档为doc格式</span></div> </div></div></a>';
