我们在对高中数学进行学习的过程中,能够清楚的知道其中存在着很多的重难点,在对这些知识进行学习的时候,必须要在不断的实践与反思中总结学习的经验。而等差数列以及等比数列是其中重要的知识点,我们在对学习时候总是存在着很多问题。本文就当前我们学习等差数列和等比数列时存在的问题进行分析,继而举出实际的例子对相关的问题进行解答,阐述其详细的解题思路以及方式。 In the process of learning high school mathematics, we can clearly know that there are many difficulties. When we study these knowledge, we must sum up the learning experience in continuous practice and reflection. However, arithmetic series and geometric series are important knowledge points. We always have many problems in learning. In this paper, we analyze the problems existing in the study of equal-difference and equal-number sequences, and then give practical examples to answer related questions, and elaborate their detailed ideas and ways of solving problems.
