Does it mean that installed app takes up more space after it each update?

Lets say my app takes up 50mb after I installed it for the first time.
Everytime when I update my app (in google playstore), I see it downloads about 10mb file size and updates the app.

1. Is the downloaded update file is 10mb? Or is 10mb added to the total size of the installed app?
2. If 10mb is the size of the update downloaded file, does the downloaded file automatically gets deleted after it is installed?
3. What is the file size that is added to the installed app? (if the playstore downloads a 10mb update file)
4. Lets say if the app has an update each month, does it mean that the app will take up additional 100mb after 10 months of updates? If lets say my app takes up 50mb after I installed it for the first time, after 10 updates (10mb each update) the app size is it will become 150mb?

Thanks

Yes. Each update adds to the overall app size. It varies by update, but it will tell you when you click update.
