You can use 'from' and 'goto' blocks from simulink-->signal routing library.

But how to update a1 to a2 to a3,I am trying for loop ,,but not getting how to work with for loop subsystem

Hey, in your case you don't have an algebrical loop because your operations are in ''cascade'' (english translation of a french word, I don't know if it's understandable). If you want to create one, you have to make an operation like a1 = a + a1.
