beginner help in counting

[yamna midhat]

I am a beginner that barely has a clue.  This is my first post here. I am trying to loop a count so that it increases based off input.  (i.e. if you entered 500 terms and wanted to increase the steps by 100 the output would be 100, 200, 300, 400, 500.) I am really lost and don’t quite even know where I am lost.  I have tried to use the debugger but I am not understanding the equation to even understand the debugger.  Any help would be appreciated.  below is what I have done.
