Can iPad model mh182B/A update to iPadOS 18.0?

You appear to have an iPad Air2 (64GB, WiFi Only).

The iPad Air2 can be updated to iPadOS 15.8.8 - this being the last update for this model. The iPad Air2 fundamentally does not support iPadOS 16 or later.

For information, here is a list of the highest version of iOS supported by the older models of iPad (for simplicity - “generations” are shortened to a number) that are restricted in their ability to be updated:

32-bit devices (obsolete)

iPad1 - iOS 5.1.1

iPad2, iPad3 and iPad mini1 - iOS 9.3.5 (WiFi Only models), iOS 9.3.6 (WiFi+Cellular)

iPad4 - iOS 10.3.3 (WiFi Only), iOS 10.3.4 (WiFi+Cellular)

64-bit devices

iPad Air1*, iPad mini2* and iPad mini3* - iOS 12.5.8

iPad Air2*, iPad mini4* - iPadOS 15.8.8

iPad5*, iPad Pro (9.7"/12.9" 1st generation)* - iPadOS 16.7.16

iPad6, iPad Pro 12.9" 2nd generation*, iPad Pro 10.5" - iPadOS 17.7.11

iPad7 - iPadOS 18.7.10

iPad8, iPad Air3, iPad mini5, iPad Pro 12.9" (3rd generation), iPad Pro 11" (1st generation) - iPadOS 26.7.1

(*) obsolete

Newer models are all able to be updated to the current version - iPadOS 27.0.1 - or optionally iPadOS 26.7.1

• iPad Pro 13" (M4/M5)
• iPad Pro 12.9" (4th generation and later)
• iPad Pro 11" (2nd generation and later + M4/M5)
• iPad Air (4th generation and later + M2/M3/M4)
• iPad (9th generation and later + A16)
• iPad mini (6th generation and later + A17 Pro)

If your iPad is not capable of update to a more recent version of iPadOS than is currently installed, should you wish to use Apps or services that require a higher version than your iPad is capable, your only option is to replace your iPad with a much newer or current model iPad.

Thank you for prompt reply.

You're very welcome. I'm sorry that this was likely not the outcome that you were hoping for.
