When you are working with complex screens like multiple fragments and activities, I would recommend you to just use an event-driven library, like:

It's going to let you transform this:

No EventBus

into this:

With EventBus

Check this post for a detailed explanation about the use cases of these libraries.

May be like this;

In fragment:

Intent i = new Intent(getContext(), Activity2.class);
i.putExtra("data", data);
getActivity().startActivityForResult(i, REQUEST_CODE);

In activity(2):

Intent resultIntent = new Intent();
resultIntent.putExtra("data", data);
setResult(Activity.RESULT_OK, resultIntent);
finish();

And in activity(1):

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     if (requestCode == REQUEST_CODE) {
     // Make sure the request was successful
         if (resultCode == Acitivity.RESULT_OK) {
             String stringData = data.getExtras().getString("data"); 
             // Data can be string, int etc. or serializable
             // YourObject object = (YourObject) data.getExtras().getSerializable("data");
        }
    }
}
