Airtable Formula

[Airtablenewbie1]

Hello everyone
Please I need help with a formula
I have a field of start date, a duration field and an end date field.

I need an airtable formula that once I put a start date and the duration of the project (2days) the end date automatically populates.

That is I have a project starting 2/1/2023 and my duration is 3 I.e 3days..I want the end date to automatically populate as 5/1/2023
