Sequences and Series : A.P.
Sequence:- The group of numbers based on a pattern.Eg:- 1,5,9,13................
Eg:- 1,2,4,8,16.............
Types of Sequence :-
1. Finite:- The sequence having limited number of terms.eg:- 1,3,5............99
Terms of sequence an /Tn-nth term of sequence
n=123............
2. Infinite:- The sequence having unlimited number of terms eg:- 1,2,3,4,.........
Series:- Let t1, t2, t3,t4,...............tn are n terms of sequence then t1+t2+t3+..........+ tn is called series. eg:- 1,2,4,8...........sequence
eg:- 1+2+4+8+.............series
