Why is this the answer?

The answer is david because this is a super sneaky and clever word puzzle that uses ancient Roman numbers and letters. To solve it, you have to be a detective and change the secret numbers back into letters. It is like a secret code about a name that you must unlock! Let us look at the first clue: "Five hundred begins it." In Roman numbers, which are the old-fashioned letters that stand for numbers, the letter that stands for the number 500 is the big letter D. So, the name starts with D. That is a great start! Now look at the end: "five hundred ends it." The riddle uses the same number, 500, to tell us the last letter. That means the name must also end with the letter D. So far, we have D _ _ _ D. Next, the riddle says, "Five in the middle is seen." The Roman number for the number 5 is the letter V. That V is going to go right in the middle of our mystery name, right between the two D letters. Now we have D _ V _ D. That V is right in the center, just like the clue said. The final part is the cleverest of all! It says, "First of all figures, the first of all letters. Take up their stations between." "First of all figures" means the number 1. The Roman number for 1 is the letter I. "The first of all letters" means the very first letter of the alphabet, which is A. The clue says these two letters, A and I, take their spots in the remaining empty places between the D, V, and D. If we put all the letters we found in the right order, they spell out D A V I D. David is the name of a very famous and important king from a long time ago, which is why the riddle mentions an "eminent king." You had to use your math skills, alphabet knowledge, and your detective skills to crack this word code! This riddle is a wonderful example of how words can play tricks on us.
