Toggle multiple divs with one button

I´m trying to "toggle" multiple divs with just 2 buttons (one for SHOW and the other for HIDE ) in relation to the last div showed by the function, with SHOW and HIDE

So, if I click one time (on SHOW), it must display div with class num1. If I click again, div with class num2 until num5. But, if I click on HIDE, it must hide the last div showed. Is this possible?

You could try to do it like this:

Use an index to store the last class shown.

Everytime you click on the show button increment this index and then $(".num"+index).show() this class.

If you click the hide, do $(".num"+index).hide() and then decrement the index
