The process of determining the sum of a series incorporates the addition of every term in a given sequence. This process necessitates a clear comprehension of the type of series: whether it's arithmetic, geometric, or different. The sums of arithmetic series can be determined using the formula n/2*(a+l), while the sums of geometric series can be obtained applying the formula a/(1-r), where 'n' signifies the total number of terms, 'a' represents the initial term, 'l' corresponds to the final term, and 'r' is a reference to the common ratio.
