An arithmetic sequence refers to a series of numbers separated by a constant difference between adjacent terms. The formula used to solve the sum of an arithmetic sequence is: n/22a + (n-1)d, where n = the number of terms to be added, a = the first term, and d = the constant val...

Proof1: formulas for nth term an d sum of terms Show that the sum of an arithmetic series is given by:Where$$ S _ { n } = \frac { n } { 2 } [ 2 a + ( n - 1 ) d ] $$a= first termd= common difference n= number of terms ...
We know that the general form of an odd number is (2n - 1) where n ≥ 1 is an integer. Also, consecutive odd numbers have a common difference of 2. Therefore, the series of odd numbers form an arithmetic progression. The sum of n odd numbers formula is described as follows, Sum ...
