How many states border 7 other states?

Answer 1

States that border 7 other states:

Arkansas

Colorado

Kentucky

Pennsylvania

Wyoming

(The states of Tennessee and Missouri border 8 states, which is the most.)

Answer 2

Four U.S. states are each bordered by only seven other states. Two of the four, Kentucky and Colorado, are each bordered by seven U.S. states, and the other two, New Mexico and Arizona, are each bordered by five U.S. states and two Mexican states.

Kentucky is bordered by Virginia, Tennessee, Missouri, Illinois, Indiana, Ohio and West Virginia.

Colorado is bordered by Oklahoma, New Mexico, Arizona*, Utah, Wyoming, Nebraska and Kansas.

New Mexico is bordered by Arizona, Utah*, Colorado, Oklahoma, Texas, Chihuahua and Sonora.

Arizona is bordered by California, Nevada, Utah, Colorado*, New Mexico, Sonora and Baja California.

Additionally, Pennsylvania and Idaho are each bordered by six U.S. states and one Canadian province, Minnesota is bordered by five U.S. states and two Canadian provinces, and Montana is bordered by four U.S. states and three Canadian provinces.

* I assume some would not consider Colorado and Arizona or New Mexico and Utah to be border states since their border is a single point. However, considering that it's possible to stand in Colorado and Arizona or New Mexico and Utah at the same time, they are included. (The point where you can be in Arizona, Utah, Colorado and New Mexico at the same time is actually a tourist attraction.)
