纵观近几年的高考,在解答题中,有关数列的试题出现的频率较高,不仅可与函数、方程、不等式、复数相联系,而且还与三角、立体几何密切相关;数列作为特殊的函数,在实际问题中有着广泛的应用,如增长率,减薄率,银行信贷,浓度匹配,养老保险,圆钢堆垒等问题.这就要求同学们不仅熟练运用有关概念,还要善于观察题设的特征,联想有关数学知识和方法,迅速确定解题的方向,以提高解数列题的速度.
Looking at the college entrance examination in recent years, in the answer questions, the frequency of test questions related to series is high, not only related to functions, equations, inequalities, and complex numbers, but also closely related to triangular and solid geometry; The function has a wide range of applications in practical problems such as growth rate, thinning rate, bank credit, concentration matching, pension insurance, round steel piles, etc. This requires that the students not only use the relevant concepts, but also be good at observing. The characteristics of the title, association of mathematical knowledge and methods, quickly determine the direction of the problem, in order to increase the speed of solving the number of questions.
