Yes, this reads as either "let n be an element of the natural numbers" or more simply "let n be natural"

Let n be an image of Arnold Schwarzenegger in the wilderness surrounded by animals with social media icons overlayed because someone was too lazy to spend 10 seconds finding a clean copy of the image.

I think it's let n contain the set of all natural numbers?

No, that symbol means "element of"

Denotes set membership, and is read "is in", "belongs to", or "is a member of". That is, x ∈ S means that x is an element of the set S.

Good thing I already passed whatever math class used that symbol and got my degree! 😅
