Evaluating the partial sum of a arithmetic series

The video tutorial explains how to calculate the partial sum of an arithmetic series starting from 10 to 100 using the formula S of N = n / 2 * (A sub 1 + A sub N). It clarifies the number of terms involved, emphasizing the inclusion of the starting term, and demonstrates the calculation of the first and last terms. The tutorial concludes with the final sum calculation, ensuring understanding of the arithmetic sequence concept.

What is the main challenge of calculating the partial sum of the series manually?
