Beginning document on a page number other than “1” [duplicate]

How do we create a new document starting on different pages? (Such as the first page of the document starts on 3 instead of 1.)

If I correctly understand your question: you want the first page of your document to have the pagenumber 3,then it can be simply done with a \setcounter{page}{3}, at the begin of your document body (right after \begin{document})
