algorithm to sequence pattern mining

does anyone know if there is a algorithm that is able to find sequential pattern from unorganised data. Details are described below along with the screenshot.

Info : First column is my original data. there are multiple set of activity being done there most of them are in order but there are not little of them that are not in order. Final output is shown in the last column/

Question: how do I find the sequence of the activity based on the the frequent order of the activities?

current way to help finding a solution :start looking at the most frequent data and how frequent it is might be adjusted by the user(?). After getting the most frequent data, it then comes to a question of what algorithm or how do I get the rough sequence of the activities?

I am not sure if my current workaround to get into the solution is right but if there is an efficient way, then that is even much better
