Sums - Series of Integers M to N - Equation to Text (Level 1)

These problems focus on interpreting mathematical expressions to find the sum of consecutive integers within specified bounds. The tasks involve converting algebraic expressions that represent sums of series (using formulas such as \(\frac{n(n+1)}{2}\) and variations of it subtracting a partial sum) into verbal descriptions of the range of integers summed. Each problem requires understanding of sum formulas and manipulation of sequences to ascertain which consecutive integers are being summed. This math topic is part of a larger unit on advanced patterns and sums.
