Uma abordagem de sequências numéricas no ensino médio

Abstract

The objective of this paper is to present a proposal which will serve as a tool helping in the study of numerical sequences, a common subject among basic mathematics studies. The teacher, through the concepts and the proposal presented in this paper, will take the advantage of all the students everyday life situations and create solution for their problems, which are recursively, and angage in numerical sequences. This approach will be presented in three parts: the first approach is the study of numerical sequences though the history of mathematics, subsequently present examples of everyday life, from nature and curiosities ralating numerical sequences, which are solved recursively, and finally, it is presented definitions and properties of arithmetic and geometric progressions and the Fibonacci sequence. The purpose of this work is to make use of recurrence in problem solving involving numerical sequences in basic education. We believe this new approach in the study of numerical sequences will help teachers to conduct a more contextualized work and students will be more motivated and feel less difficulty in learning the mentioned subject.
