Key Concepts of Sequence and Series
1. Arithmetic Sequence (AP)
A sequence in which each term is obtained by adding a fixed value (common difference, d) to the previous term.
Formula:
2. Geometric Sequence (GP)
A sequence in which each term is obtained by multiplying the previous term by a fixed value (common ratio, r).
Formula:
3. Sum of Geometric Series
The sum of the first terms of a geometric sequence:
Formula :-
4. Sum of Infinite Geometric Series
If , the sum of an infinite geometric series is given by:
Formula : -
5. Sum of Arithmetic Series
- The sum of the first terms of an arithmetic sequence:
- Formula :-
Conclusion
