Sums - Series of Integers M to N - Equation to Sum

This math topic focuses on calculating the sum of integers within a specified range using a formula. The problems require determining the sum of consecutive integers from a given lower bound \( M \) to an upper bound \( N \), using an equation in LaTeX format. The equations incorporate the method of summing the first \( N \) integers and subtracting the sum of the first \( M-1 \) integers, leveraging the properties of arithmetic sequences. Students practice these skills through multiple-choice questions, each offering different numeric options as potential answers.
