高中数学十分注重考查同学们的逻辑思维能力与抽象思考能力,数列问题尤为突出。因此我们在学习数列问题时要掌握解题技巧,这样解题效率就能大大提升。一、深入了解数列问题的本质数列是以整数集或者是其它有限个的子集构成定义域的函数,其本质是一种函数。它的排列是呈规律性的,包含在其中的每一个数都可以称之为数列的某一项,第2个数就称之为数列的第2项,第n+1个数就称之为数列的第n+1项,通常用an+1来表示。数列的一 High school mathematics attaches great importance to examining the students’ logical thinking ability and abstract thinking ability. Therefore, we must master problem-solving skills when learning series problems, so that the efficiency of problem solving can be greatly improved. First, in-depth understanding of the nature of the series of problems The sequence is a function of the domain defined by a set of integers or other finite subsets, the essence of which is a function. Its arrangement is regular, each number contained in it can be called an item of a sequence, the second number is called a second item of a sequence, and the n+1 number is called The n+1th item of the series is usually expressed as an+1. One of the series
