Creating a sequence of shapes appearing and disappearing after certain time intervals

Hello,

I am a newbie in UE and hence I am sorry in advance if my question sound silly. I want to create a sequence of shapes appearing and disappearing after certain time intervals. For example, at the beginning a cube appears. Then after 1000 miliseconds it disappears and then after 1000 miliseconds a sphere arrives and it also disappears after 1000 seconds. And it goes on like this. Can anyone please help me on how to proceed on this problem. Thanks a lot in advance.
