What letter must replace the "(?)" in this finite sequence? Explain.

A, A, A, A, (?), A, A, A, A, A, A, __, __, __, __, __, __, A, __, ... , A.

Hint:
All "A"s are present, and the last "A" shown is the final letter of the sequence.

(In reply to re(2): Not quite a guess. by Leming)

Following on from Dej Mar, that was rather insightful.

While not trying to give too much away during the review, pcbouhid did make a comment that he could put a "U" as the beginning of the then ellipsis series.  That would have equated to "Mu" the first "_" character in the sequence.

Well done!
