A more thorough explanation:

Definition:

Subsequent, adjective. This word describes something that happens later, after something else has already happened.

Examples:

• After the initial meeting, there were subsequent discussions about the project.
• The company released subsequent versions of the software to fix bugs.
• She failed her first test, but subsequent tests showed improvement.

Explanation: The examples show how subsequent is used to describe something that happens after something else. In the first example, subsequent discussions happened after the initial meeting. In the second example, subsequent versions of the software were released after the first version had already been released. In the third example, subsequent tests were taken after the first test had been failed.
