ELI5: Explain Like I'm 5

Sequential logic

Sequential logic is like a game you have to follow the rules of. To play the game you have to remember the order in which things happen, and then what should happen next. The order is like a list of instructions that you have to go through one step at a time, like "First do this, then do this, then do this". This can be used in computer programming to tell a computer what to do and in what order, making it easier to get the right answer.
