It has not been officially confirmed that she is the last of the seven, only that she would be one of the narrators of The Mark of Athena. Also, Annabeth is smart, but her bases are kind of covered (as Frank is skilled in tactics and Piper has knowledge about mythology). As far as who it could be, Frank mentioned stories about Roman campers that left Camp Jupiter to train in the Greek style, possibly hinting to a third camp where a child of Minerva/Athena could be. Don't say things are facts before they are confirmed to be true.
