I have requirment where I have to add two constant numbers with increment of 1, a=constant b=constant

a1=a+b; a2=a1+b; a3=a2+b; a4=a3+b;

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

a1=a+b( for a1(tag name) use goto block to store the value(either 'local' or global), then do continuously..

This doing continuosly am not getting,how to continue it with increment of a1 a2 a3 a4

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.
