Notes for teachers

 * 1) An arithmetic progression is a sequence in which each term is obtained by adding a fixed number to the preceding term.
 * 2) General form : a, a+d , a+2d , a+3d, . . . . ., a+(n-1)d
 * 3) Common Difference (d) : Difference between any term and its preceding term
 * 4) Formula's of Arithmetic progression

Learning objectives

 * 1) Defining an Harmonic progression
 * 2) The General form of Harmonic Progression
 * 3) Compare H.P with other type of progression
 * 4) Identifying H.P among a given set of progression

Notes for teachers
A sequence in which, the reciprocals of the terms form an arithmetic progression is called a Harmonic progression.

Learning objectives

 * 1) Defining G.P by recognizing common ratios
 * 2) General form of G.P
 * 3) Terms used in G.P
 * 4) Identifying next term and precedig term of an 'n' th term of G.P
 * 5) Finding the common ratio, a specific term and the last term of G.P
 * 6) Formulating the formula 'n'th term of G.P, sum formula based on 'r', Sum of infinite formula,

Notes for teachers

 * 1) A geometric progression is a sequence in which each succeeding term is obtained by multiplying the preceding term by a fixed number.
 * 2) The ratio of a term and its preceeding term is called common ratio (r).

Notes for teachers

 * 1) Arithmetic mean of two numbers is equal to half of their sum.
 * 2) The harmonic mean of any two numbers is equal to twice their product divided by their sum.
 * 3) The Geometric mean of any numbers is square root of their product.
 * 4) Geometric mean is equal to square root of their product of arithmetic mean and harmonic mean/
