Expert Answer:

We would request you to please ask one question at a time. The answer to your first question is as follows:
 
The given situation forms an AP, if we look at the number of students left in the audotorium after when each batch went out.
 
In that case, the AP would be:
500, 470, 440, 410, ...
 
Here, first term = 500
common difference = -30
