Rapid Miner Linear Regression

Dear all, 

we used the attached data to do a linear regression.  
The question is: 

1.   Predict, how many cases start during the next 5 days after the last case started?

The result of my linear regression is 3.5, but I am not sure if I did a mistake. 

Can you please help me? 

I used the following operators. I filterd the activity (=register request)

    If you are forecasting the number of cases in the next five days, you need to transform the running examples into time series. You will record the number of cases started in each day. You can also aggregate the running examples at the case level, with the attributes like starting timestamp, ending timestamp, ... for each case. No model would be a good fit at the level of this running example.
