• emailed, texted or messaged the photos to friends or family
• iCloud photo sync
• iCloud backup
• iTunes backup
• Transfer your photos to your computer via USB cable
• Apple Photo Stream
• Sync to Google Photos
• Sync to some other photo archiving service such as Shutterfly
• Sync to Dropbox
• Sync to box.com
• Sync to Microsoft OneDrive
• Sync to Amazon Photos
• back up to Livedrive
• Backup to any other backup or archiving service

If the answer is no to all of the above your photos and videos are gone forever.

When you delete photos and videos from your iPhone, you will have about 30 days to recover until it is permanently deleted.

To find that deleted photos and videos e you to

Photos>Albums>Recent deleted (scroll all the way down to find)
