What are some examples of a sequential-decision tasks?

Just trying to get some intuition on what sort of problems out there are categorized as "sequential" while others "non-sequential"

Thanks :)

Solution

A great example of a non-intuitive sequential decision problem (with a nice and neat solution), is the Pandora search problem:
