In what sequence may each continue driving?

Your answer is correct because the cyclist has priority in this situation. According to German traffic rules, when you are at an intersection with a "priority road" sign (the yellow diamond) and a side road on the right, vehicles on the priority road have the right of way.

Here’s the sequence:

1. The cyclist is already on the priority road and turning left, so they go first.
2. You, driving straight on the priority road, go next.
3. The yellow car is coming from the side road and must yield to traffic on the priority road, so it goes last.

Understanding the priority road sign and yielding to vehicles on the priority road is key to correctly deciding the sequence at intersections like this.
