数列极限是高中数学重要内容,又是初等数学与高等数学的重要衔接点,所以在历年的高考中都占有重要的地位.它在高考中直接考查的题目多为选择题、填空题,间接考查数列极限问题大都渗透到解答题中,除与数列求和外,有时还会与其他知 The series limit is an important part of high school mathematics, and it is also an important connection point between elementary mathematics and advanced mathematics. Therefore, it has occupied an important position in the college entrance examination over the years. The topics it directly examines in the college entrance examination are mostly multiple-choice questions, fill in blank questions, and indirectly examine Most of the limit problems of the series have infiltrated the answers to the questions.
