在高中数学中,数列是重要的学习内容,同时数列也是函数部分的延续,是函数的另一种表现形式,是各个知识的交汇点。因此历年来高考都会考查数列,并且以中高档题为主,主要考查的题型有:数列的通项公式、递推公式和前n项和公式。数列还常常结合指数、对数函数以及不等式等内容一起考查,难度相当大。由于数列题综合性较强,具有相当的难度和深度,所以对同学们的解题能力有较高要求。同时,数列在日常生活中的应用也十分广泛。比如
In high school mathematics, the series is an important learning content, while the sequence is also part of the continuation of the function is another manifestation of the function, is the intersection of various knowledge. Therefore, over the years the college entrance examination will test the series, and in the high-grade questions mainly the main exam questions are: series of general formula, recursion formula and the first n terms and formulas. The numbers are often difficult to combine with indices, logarithms and inequalities. Due to the comprehensiveness of the series of questions, with considerable difficulty and depth, so students have a higher ability to solve problems. At the same time, the use of numbers in everyday life is also very broad. such as
