Sums - Series of Integers 1 to N - Addition to Sum (Level 3)

This math topic focuses on finding the sum of series of consecutive integers from 1 to a specified number (N). It practices calculating the sum of these integers for various values of N, helping students understand the properties of arithmetic series. Each problem presents a sequence and asks for the total sum, providing multiple choice answers to verify the student's calculation. This set of problems is part of an advanced unit on number patterns and patterning, aimed at enhancing calculation skills and understanding patterns within number sequences.
