Arithmetic Progressions
Key points
1. SEQUENCE : - A set of numbers arranged in some definite order and formed according to some rules is called a sequence.
 
2. PROGRESSION :- The sequence that follows a certain pattern is called a progression.
 
3. ARITHMETIC PROGRESSION :- A sequence, in which the difference obtained by subtracting from any term its preceding term is consistent throughout, is called an arithmetic sequence or arithmetic progression (A. P.). The general form of an A.P. is a, a+d, a+2d, . . . .
 
4. GENERAL TERM :- If 'a' is first term and 'd' is common difference in an A.P. then nth term (general term) is given by an = a + (n –1)d .
 
5. SUM OF n TERMS OF AN A.P. :- Sum of first n terms of an A.P. is given by :-
Sn = n/2 {2a+ ( n–1) d}
 
where, a : first term, d: common difference.
If l is the last term of a finite A.P., then the sum is given by Sn =n/2 {a+l }
 
6. (i) If  an is given, then common deference d = an– an-1 
(ii) If  Sn is the sum of n terms of an A.P., then nth term is given by an = Sn - Sn-1
(iii) If a sequence has n terms, its rth term from the end = its ( n-r +1)th term from the beginning.
(iv) If a, b, c are in A.P., then b= a+c/2
