Mathematics teaching should not only follow the process of knowledge development and development, but also focus on the accumulation of students’ existing knowledge and experience. On this basis, it is a purposeful design of reasonable and effective inquiry activities, and guided by the correct method, it is possible to mobilize students. The enthusiasm and enthusiasm of learning stimulates their learning potential. In the process of rediscovering and recreating personal knowledge, it is easy to grasp the nature of the problem, build a reasonable knowledge structure, and effectively enhance their ability to explore thinking. Xianghe is the final section of the Jiangsu Education Edition “Ordinary High School Curriculum Standards Experimental Textbook Mathematics (Compulsory 5)” and “Number Series” chapters. It is the relevant knowledge and method for equal-difference and geometric progression.
