based off of westward migration and settlement, which states most likely joined the nation last?

I'm not sure what it could be

No. Alaska and Hawai'i were the last states to join the union in 1959. Arizona and New Mexico were the last ones before that, in 1912. Generally, though, the inland and western states did join the union as they became populated and organized governments, yes. I'm not sure what your question is asking you to figure out.

(California was admitted as a state in 1850.)

Determining which states most likely joined the nation last based on westward migration and settlement requires examining historical trends and events that occurred during the westward expansion of the United States. Here's how you can approach finding the answer:

1. Gather historical knowledge: Familiarize yourself with the timeline of westward migration and settlement in the United States. This could include events such as the Louisiana Purchase, the Oregon Trail migration, the California Gold Rush, and the Homestead Act of 1862.

2. Study territorial acquisitions: Understand which territories were added to the United States through various acquisitions and treaties. These acquisitions expanded the western boundaries of the nation and eventually led to the addition of new states.

3. Analyze settlement patterns: Consider the order in which settlers established permanent settlements in different regions. Look at factors such as the availability of land, access to natural resources, economic opportunities, and the presence of indigenous populations.

4. Consider historical context: Take into account factors such as political climate, the pace of territorial organization and statehood admissions, and significant events like the Civil War that could have affected the timing of state admissions.

By following these steps, you can gain a comprehensive understanding of the westward expansion and settlement patterns, which will help you determine which states most likely joined the nation last.
