a = first term,n = position of the termd = common differenceNth Term of Arithmetic ProgressionThe formula an = a + ( n – 1 ) d is used to get the general term (or) nth term of an arithmetic progression (AP) whose first term is a, and the common difference is d. ...
The general term (or)nthterm of an APwhose first term is 'a' and the common difference is 'd' is given by the formula an= a + (n - 1) d. For example, to find the general term (or) nthterm of the progression 6, 13, 20, 27, 34,. . . ., we substitute the first term,...
