The answer to this riddle is the letter "e." It appears once in the word "second," once in "minute," twice in "century," and not at all in "thousand years." Each time, the presence of the letter varies, reflecting its frequency in the respective words.
How about the letter E.
There are not a thousand years in a century. There are a hundred years in a century. A thousand years is ten centuries.
No, one thousand years is not in a century. A century consists of 100 years, so one thousand years equals ten centuries.
The letter "m".
