数列既是高中数学的主干知识,又是学习高等数学的基础,既具有函数的特征,又能构成独特的递推关系,因此新课程改革后数列仍然是高考考查的热点问题,但题型由过去单纯考查数列知识或递推数列问题转化为在题型创新、知识交汇上做文章,由此设计了许多层次恰当、形式新颖的创新性问题,使 The sequence is not only the backbone knowledge of high school mathematics, but also the basis for learning advanced mathematics, both with the characteristics of the function, but also constitute a unique recursion relationship, so the new curriculum reform is still the number of columns in the college entrance examination examination of hot issues, but the type from the past Simply examining sequence knowledge or recurrence sequence questions into problem-based innovation and knowledge intersection make an issue, which designed a number of appropriate and innovative forms of novel problems, so that
