摘要: 對(duì)數(shù)列規(guī)律的把握就是想法知道數(shù)列的通項(xiàng),在求數(shù)列的通項(xiàng)問(wèn)題中,一種是已知數(shù)列的項(xiàng)或者前幾項(xiàng)求數(shù)列通項(xiàng),另一種是已知數(shù)列的遞推式求數(shù)列通項(xiàng),特別是遞推式中含根式時(shí),求數(shù)列通項(xiàng)顯得更復(fù)雜一些,本文針對(duì)含根式的遞推式展開(kāi)討論,給出數(shù)列通項(xiàng)模型,較好地解決了一類(lèi)根式遞推式數(shù)列的通項(xiàng)問(wèn)題,并得到一般結(jié)論.
