# Thread: How do I predict how a number will evolve based on its evolution in a short span?

1. ## How do I predict how a number will evolve based on its evolution in a short span?

Greetings,

First of all I am sorry if this has been posted before [I have tried searching] and/or if it seems like a beginner's question.
Now on with the question: Let's say we have a number X, we monitor it for 10 time units, in these 10 time units, the number changes value [based on user input] 6 times like so:

1. X + 1
2. X + 1
3. X + 1
4. X - 1
5. X + 1
6. X + 1

*The complete evolution would be something like*

1. X + 1
2. X + 1
3. X + 0
4. X + 0
5. X + 1
6. X + 0
7. X - 1
8. X + 1
9. X + 1

*It is also possible that X + 0 is in actuality X + 4 - 4 [think vote system]*

The number thus becoming X + 5 in a 10 time unit interval.
Based on this information, is it possible to predict how the number will evolve?
I am really interested in the theory behind this so if you could further direct me to information sources it would be great!

Thank you,
