GEOMETRIC PROGRESSION

                                                     GEOMETRIC PROGRESSION (GP) SEQUENCE:    A Sequence is a function whose domain is the set of numbers or a subset of the natural numbers .Here the co-domain is the set of real numbers (complex numbers) If range is a subset of real numbers then the sequence is called is called real sequence SERIES : By connecting the terms of a sequence with the mathematical operators ,we get a series.   PROGRESSIONS: It is not necessary that the terms of a sequence ,always follow certain pattern ,or they are described by some explicit formula for the nth term. Those sequences whose terms follow a certain pattern are called progressions .The progressions are of 4 types  1. ARITHMETIC PROGRESSION 2. GEOMETRIC PROGRESSION 3. HARMONIC PROGRESSION 4.ARITHMETIC -GOEMETRIC PROGRESSION     ...
