If required for the partial sum from mth to nth terms, the following formula can be used S=n−m+12(am+an)S=n−m+12(am+an) or S=n−m+12[2am+(n−m)d]S=n−m+12[2am+(n−m)d] Back to top Geometric Progression,
Arithmetic Sequence and Sum Formulas Formula n-th term: an=a1+(n–1)dn-th term: an=a1+(n–1)d Sum of first n terms: Sn=n2[2a1+(n–1)d]Sum of first n terms: Sn=2n[2a1+(n–1)d] Explanation: a1a1 is the first term dd is the common difference nn...
Assume that there are 'm' terms in an AP (Arithmetic Progression) in total whose first term is 'a' and the common difference is 'd'. Then the formula for the nth term from the last of AP (its position from first would be (m-n+1)th position) is: Tm-n+1 = a + (m-n+1-1...
Since we don't know the total number of terms in the arithmetic progression it is really difficult to find the sum of such AP by using the formula of sum of n terms ie Sum of AP = {n(n+l)} /2 Where, n = number of te...
