由于高考数学客观题只需要给出正确答案而不需要解题过程,因此客观题解答的速度与全卷的考试时间的分配对所能取得的成绩有很大的影响。下面以近年来新课标高考数列真题及模拟题为例,谈谈求解高考数列客观题的快速求解策略。策略一紧扣定义若已知一个数列是等差或等比数列,则可以利用等差数列或等比数列的定义直接求解相关量。例1(2013年江西卷)等比数列x,3x+3,6x
Since the mathematical objective question of the college entrance examination only needs to give the correct answer without solving the problem, the speed of objective question answering and the distribution of the whole examination time have a great influence on the achievements. The following in recent years, the new curriculum standard college entrance examination Zhenti series and simulated questions, for example, to talk about the objective solution to the number of college entrance examination quick solution strategy. Policy Definition If you know that a series is an arithmetic or geometric series, you can use the definition of arithmetic progression or geometric series to solve the correlation directly. Example 1 (Jiangxi Volume 2013) Equal to the series x, 3x + 3,6x
