When Apple introduced the iPhone 6s Plus in September 2015, it ran iOS 9.0. You can update an iPhone 6s Plus to the latest release of iOS 15.

You can't update an iPhone 6s Plus to iOS 16, 17 (the current version), or 18 (which will soon be the current version). For that phone, iOS 15 is the end of the line.
