If an answer is deleted on Programmers and the author wants to ask about the reason on MetaProgrammers, how can he do it? How can he reference something that doesn't exist? He can't edit it, either, it is unseen.
You have 9 deleted answers on Programmers. 7 of those were deleted when the question was deleted, one you deleted yourself and the more recent one was deleted by three community members. I'm guessing that's the one you are looking for, here's the link to the question: How to indicate that a class might implement an interface?.
As ChrisF already mentioned, you should be able to see your answer now that you have a link to the question. You can also edit and improve it - as is, it's more of a comment than an actual answer to the question.
You can always see your deleted answers (regardless of your reputation) when viewing the question. So as long as you have (or can find) a link to the question you can then find the the link to the answer.
Of course, only moderators or 10K+ users will be able to see your answer, so it would be best to include the text of the answer in your Meta question.
