Which state is NOT one of the original 13 states?

The state that is not one of the original 13 states is Washington. The original 13 states were the colonies that declared independence from British rule and later formed the United States. These states include Virginia, New Jersey, and Massachusetts, which were all among the original colonies established in the 17th and 18th centuries.

Washington, on the other hand, was admitted to the Union much later, in 1889. It was not one of the original colonies and was instead part of the Pacific Northwest, with a history of being populated and developed after the founding of the United States. Therefore, Washington’s status as a state is significantly different from that of the original 13 colonies, making it the correct answer to the question.
