To find the intersection of sets $A$ and $B$, denoted $A \cap B$, we need to identify the elements that are present in both sets.

Given:

• $A = \{5, 6, 7, 8, 9, 10, 11, 12\}$
• $B = \{3, 5, 7, 9, 11, 13\}$

Now, let's find the common elements in both sets:

• Common elements: $5, 7, 9, 11$

Thus: $A \cap B = \{5, 7, 9, 11\}$

Let me know if you would like further details or have any questions!

Here are 5 related questions you might explore:

1. What is the union of sets $A$ and $B$?
2. How would we find $A - B$ (the difference of $A$ and $B$)?
3. What are subsets and how would we determine if $B$ is a subset of $A$?
4. How would we express $A \cup B$ using only elements from $A$ and $B$?
5. What is the symmetric difference between $A$ and $B$?

Tip: To check for intersections in larger sets, list elements systematically to avoid missing any.
