Begging the question means assuming the conclusion. In this type of argument, the conclusion that is sought to be proved is included in the initial premises/reason of the argument.

Begging the question or assuming the answer is a logical fallacy that occurs when the conclusion of an argument is used as a premise of that same argument; i.e., the premises would not work if the conclusion wasn't already assumed to be true
