Respuesta :

You always get from one term to the next by adding 6:

[tex]573 + 6 = 579[/tex]

[tex]579 + 6 = 585[/tex]

[tex]585 + 6 = 591[/tex]

[tex]591 + 6 = 597[/tex]

So, the rule is "add 6"

Answer:

Add 6

Step-by-step explanation:

If you see the equations 573+6=579

                                       579+6=585

                                       585+6=591

                                       591+6=597

they all are added by 6
