数列是初等数学与高等数学的一个重要衔接点,数列通项公式的求法是数列教学的重点和难点之一,也是历年数学高考命题的热点.本文对两类典型递推数列通项公式的求法做初步探讨. The number sequence is an important convergence point between elementary mathematics and advanced mathematics, and the method of sequence general formula is one of the key and difficult points in sequence teaching, which is also a hot topic in mathematics college entrance examination proposition over the years. Make a preliminary discussion.
