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

This math topic focuses on calculating the sum of a series of consecutive integers from a starting integer \( M \) to an ending integer \( N \). It provides practice in recognizing patterns in series and using these patterns to accurately sum a sequence of numbers. The problems presented require determining total values over ranges like 2 to 14, 24 to 35, or 19 to 32, illustrating the application of summation skills in arithmetic sequences. Each problem comes with multiple-choice answers, reinforcing critical thinking in estimating and verifying the correct sums.
