repeat loop with counter?

How would I Setup an action to repeat with x=1 up to the count of all instances of an object that exist in the layout?

The idea is to align a bunch of instances on layout creation and give the a defined offset.

The first time it would be + x

the second time + x*2

the third time + x*3

etc..

Please be specific if you can. I'm rather new to this and don't know how to use JS without the actions yet.

Thank you!

under System Loops you will find "For Each"

select the object type and it will loop through each one, each time through the loop only one of the objects will be selected, or "Picked". then as an action for the loop you can set the properties of the current object, and you can use the "LoopIndex" keyword to multiply x by (it will be 0 for the first instance of the object and will increase by one each time through the loop).

Thank you AllanR! I was missing the loopIndex keyword. That's just what I was looking for.
