Arizona, Arkansas, Georgia, Hawaii, Idaho, Indiana, Iowa, Mississippi, Ohio, Oklahoma, Rhode Island, South Carolina, Utah, West Virginia, Wyoming

It seems likely that the geographic feature you're referring to is

the state's capital city also being the state's largest city

but every source I can find shows 17 states with that quality, not 18. Those 17 are the 15 you listed plus

Colorado and Massachusetts.

For example, Wikipedia shows 17, using census data published in 2012, and there are also 17 on this handy map using 2010 census data. Is it possible you used an outdated source, or miscounted? Or did you have a completely different geographic feature in mind, making this an unbelievable coincidence?
