Delete page based on search word and one page after that

I have pdf with a hundred of pages i need to delete that contain "Wrong-File" word and following with one page after the "Wrong-File" page,

So if my pdf found 1000 pages contain "Wrong-File" word there are 2000 pages i need to delete, because after the "Wrong-File" page there are one page (the attachment of "Wrong-File" page") i need to delete

Note here : the attachment or the page after the "Wrong-File" page have no same spesific word, so i can't search the attachment and delete them.
