The sequence for an action story is exposition, rising action, climax, falling action, and resolution.
When you are writing a story, the first and most important thing you need is a good problem. You want to make your story exciting. You will also need good characters and a good setting. Put these three things together, and you have the exposition.
The beginning of a story is the exposition. In the exposition, you introduce your reader to the setting (where and when the story takes place), the characters (the people in the story), and the conflict (the problem your characters need to solve).
The second part of the story is called the rising action, because this is where the story starts to get more and more interesting. You explain the problem and have your characters deal with it. You can make it more and more challenging for them.
The most challenging part of the problem for the characters is the climax. The climax is where the story turns. The characters have to make a choice. This is the most interesting part of the story.
Finally, you have the resolution of the story. The resolution is the end. This is where the problem is solved, and your characters can go on their way.
