This paper introduces a novel formula to enhance the utilization of accumulating a bunch of series expressions sequentially whereas in terms of traditional method limitation causes in case of large datasets. The research explores advanced techniques that integrate numerical methods with distinctive analysis efficiently. Current methods often fail to work for huge expressions summation such as: n + (n-1) + (n-2) + (n-3) + … … … (n-N) where n>=N. The research aims to highlight the continuous decreasing values that sum up and furthermore, works for that equation where the values contain two constant differences. That problem also can be solved using novel formulas. If we know the values of n=given number from user, m=number of expressions, summation of natural numbers till infinity and in other case summation of two continuous deviations from second expression to last one. This method paves the way for more efficient modeling in fields such as physics, engineering, and data science, where real-time solutions are critical and time consuming. Outcome results demonstrate a significant improvement in accuracy and computational time compared to existing techniques, particularly in mathematical cases.
