## Important Topics for Hall & Knight Higher Algebra Chapter 6: Harmonical Progressions. Theorems Connected with the Progressions

**Harmonical Progression **

As the name of the chapter suggests, Harmonical Progression is the main topic of the chapter and you will be introduced to many more concepts that are related to it. You will learn that when three quantities can be expressed as a / b = a – b / b – c

Such that the quantities were a, b and c; they are known to exist as harmonical progression. When all the three consecutive terms are said to be in harmonic progression, the entire quantity (series) is said to exist as a harmonic progression.

**Properties of Harmonical Progression **

Now that you are introduced to the concept of Harmonical Progression, you will also learn about the numerous properties of these progressions. These properties are important from the point of geometry and algebra. You will learn about the general formula to find the sum of any number of quantities in harmonical progressions.

Hall & Knight Higher Algebra Harmonical Progressions. Theorems Connected with the Progressions chapter will also help you learn about the harmonic mean which is basically the quantity that is situated in the middle between two quantities (in a group of three quantities). The fundamentals of arithmetic progressions and geometric progressions are also used in order to solve the problems given in the chapter. You must refer to our study notes for the chapter for more information.
