This math topic focuses on finding the sum of series of integers from 1 to N using a specific formula. The problems present scenarios requiring the application of the formula \( \frac{n(n + 1)}{2} \) to calculate the sum of integers from 1 up to a given number \( n \). Each problem provides a selection of possible answers, testing the ability to correctly execute and apply the formula within different contexts. This belongs to a broader unit on practicing number patterns.
