MATHEMATICS NOTES CHAPTER-9
Points to Remember
We all are aware of the definition of sequence, Series and Progressions.
The sequence is a function whose domain is the set N of natural numbers.
Real Sequence: A sequence whose range is a subset of R is called a real sequence.
Series : If a1, a2, a3, a4, ………, an, ………. is a sequence, then the expression a1 + a2 + a3 + a4 + a5 + …….. + ……… + an + ……… is a series.
A series if finite or infinite according to as the number of terms in the corresponding sequence are finite or infinite.
Progressions: It is not necessary that the terms of a sequence always follow a certain pattern or they are described by some explicit formula for the nth term. Those sequences whose terms follow certain patterns are called progressions.
Difference Between Sequences and Series
Let us find out how a sequence can be differentiated with series.
