Update your iOS iPhone 7
[Re-Titled by Moderator]
iPhone 7, 15
An iPhone 6s, iPhone 6s Plus, iPhone 7, iPhone 7 Plus, or iPhone SE 1 isn't capable of 16 or above; they require an A11 or better CPU. To install 15.8.3, use a computer or the Software Update function in Settings.

You probably already have the latest iOS version for the iPhone 7. It is iOS 15.8.3.
Tap Settings > General > Software Update to check.
The iPhone 7 cannot update to iOS 16, iOS 17, or iOS 18......if that is what you are really asking.
You cannot install iOS 18 on an iPhone 7. You cannot install iOS 16 or 17 on an iPhone 7, either.
For the iPhone 7, which originally ran iOS 10 when Apple released it about eight and a half years ago, iOS 15 is the end of the line.
