Animating multiple objects in seqence

Hi, I couldnt find any similar problem on forum so I decided to ask myself.

I created an array of objects and i wanted to animate them to rotate for 360 degrees along each own center but i’d like it to do it sequentially - start in the middle of array and then expand toward the end (something like wave) but i couldnt find the way to do it. I’m not good at scripting so I’d like to avoid that.
