Actually at that part in Progressive Asuna's barely 15, she turned 15 a month and seven days before they all got stuck in SAO. It would make sense if Argo's 18 ish, she doesn't act like she's not used to being by herself and for the most part (particularly in Progressive) Argo's attitude outside of her info gathering moments is mature but not quite adult. So I could see her as about 18 or a little younger
