A company uses drones to deliver parcels to different locations. On the first day, the drone delivers \(1\) parcels, on the second day it delivers \(2\) parcels, on the third day it delivers \(3\) parcels, and so on. The company delivers a total of \(1035\) parcels over \(n\) days.

 

Answer the following questions:

1. Determine the number of days \(n\) for which the total number of parcels delivered is \(1035\).

 

• 48
• 45
• 47
• 46

2. Find the number of parcels delivered on the last day.

 

• 48
• 49
• 44
