How to create one final decision tree

I need to create on final decision tree based on 25 different decision trees but I am not sure how to do that. They need to be constructed in a sequential manner where we update the weights of the training examples based on the prediction and the error rate of the previous decision. Right now I have the random forest operator where I have 25 different decision trees but what is it that I used to create one final decision tree?

Thank you

    The process you're describing is implemented in ensemble models like Bagging and Boosting, and in Gradient Boosted Trees.

    However, these create *separate* trees. I don't see how one decision tree would be able to express all the different trees adequately and I don't know an algorithm implementing this.
