ELI5: Explain Like I'm 5

Integer sequence

An integer sequence is a list of numbers that go in order. For example, if you have the numbers 3, 4, 5, 6, 7, then you have an integer sequence because the numbers increase by one each time. You can also have a decreasing sequence, like the numbers 7, 6, 5, 4, 3. The important thing is that the numbers keep going in the same direction.
