Following are the key points that should be kept in mind while preparing this chapter in perspective of Entrance test of Universities.
Sequence and general Term.
Concept of Arithmetic Sequence , Mean , Series and Sum.
Concept of Geometric Sequence , Mean , Series and Sum of n terms.
Sum of Infinite Geometric Series in different situations.
An infinite geometric Series is Convergent if its sum is an exact number.
An infinite geometric Series is Divergent if its sum is negative or Positive Infinity.
An infinite convergent geometric Series is Oscillatory if its sum is a definite number but the sum converges to different numbers under different situations.</strong>
There is no concept of oscillation in Divergent series.
See "Math_Tip-02_Vulgar_Fractions" to solve Vulgar fractions in seconds.
Concept of Harmonic Sequence , Mean , Series and Sum.
Summations and Summation Formulae.
In this chapter results in all exercises are very important so try to memorize them.
