how to show successor and predessor on number line

We can show the successor and predecessor on number line , as we know that if we subtract -1 from the given number it is it's predecessor and if we +1 so it is it's successor so on the number line if we move one step to the left of the given number so it is it's predecessor and if we move one step to the right it is it's successor like if i take one example, 5 it's predecessor is 4 and successor is 6 now i will shoe it on the number line=
