This chapter is an introduction to the study of discrete mathematics. Sequences and series are used in calculus and statistics, which translates to multiple job professions such as engineering and statisticians.
Tomorrow we will learn about…
Geometric series and sequences; in particular finding the nth term and geometric means of a geometric sequence and the sum of n terms of a geometric series.
