Vinimetric: A Practical Rule for Calculating the General Term of an Arithmetic Progression

(Escola Estadual Embaixador José Bonifácio; Brazil)

Abstract: This paper presents an alternative for calculating the general term of an arithmetic progression. The so-called Vinimetric rule was discovered by Vinícius de Carvalho Oliveira in a 2nd year high school math class. This new approach is presented as a faster and simpler alternative to the conventional use of the formula. The work aims to validate and explore the educational potential of “Vinimetrica”, promoting discussions about new approaches to teaching mathematics and encouraging a creative and questioning school environment.

Key words: arithmetic progression, number sequence, mathematics education
