Why do we use the Fibonacci series for estimating story points in Agile project management?

The Fibonacci series is used for estimating story points in Agile project management because it allows for a more accurate and relative estimation of the complexity and effort required for different tasks. The series follows a pattern where each number is the sum of the two preceding numbers, which helps teams to better understand and compare the relative sizes of different tasks. This method helps teams to make more informed decisions and prioritize tasks effectively during project planning.
