Rapid Growth Algorithm? How?

Question

Mathematics

Hello!
Help with an algorithm that determines which of the elements shows stable and / or fast growth.
For example, there are several sites.
Site A → Jan. 100 visitors; Feb → 250 visitors; March → 450 visitors.
Site B → Jan. 15250 visitors; Feb → 14500 visitors; March → 9800 visitors.
Site B → Jan. 50 visitors; Feb → 300 visitors; March → 900 visitors.
How can you calculate which of these sites is the fastest growing?

Answer 1

Physics tells us that speeds are compared by acceleration. That is, the increment of speed per unit of time. Those. first derivative. Stability will show the second derivative.
