Question 831661
First suggestion:  What do the plotted points look like?  Can you find a clear numerical pattern?


Second suggestion:  What are you studying (topic, not necessarily just which course)?



Your data set is a simple one.  You should easily fit a (do you know what kind) function to it.



Still more direct:  Notice the point (0,-4).
What is the vertical change to horizontal change ratio for each neighboring pair of data points?
