Theo các bạn ấy giải là: H Ọ C S I N H G I Ỏ I T Ỉ N H  gồm 15 chữ cái (em đếm ra thì cũng biết rồi)

Người ta hỏi là chữ số thứ 2015 => ta lấy 2015 : 15 = 134 (dư 5) (cái này em có thể tự tính)

Thì đếm dần đi là thấy chữ cái thứ 5 là chữ I

=> Chữ cái thứ 2015 là chữ I

Chị chỉ diễn đạt lại cách mấy bạn kia giải thôi chứ không biết làm =))
