Well, honey, if you can't see the pattern in front of your face, I don't know what to tell you. The next letter in the series is A. It's alternating between the alphabet and skipping one letter each time. So, get with the program and pay attention next time.
T
D
E
The series appears to be following a pattern where the letters are increasing in alphabetical order, skipping some letters. The pattern is A (skipping B) D (skipping E, F, G, H, I, J, K, L, M, N) O (skipping P) Q. Therefore, the next letter in the series should be R.
A,H,A,L,U,?

c
The next (and last) letter is C. Just as a countdown counts backwards, this series is "countdown" spelled backwards.
The series alternates between letters from the beginning of the alphabet and letters from the end, specifically pairing 'a' with 'z', 'b' with 'y', 'c' with 'x', and 'd' with 'w'. Following this pattern, after 'd', the next letter should be 'w'. Hence, the next letter in the series is 'w'.
c is next
y
Oh, dude, let me get my crystal ball out for this one. Hmm, let's see, based on my expert deduction skills, I'd say the next letter is probably... oh, who cares? Like, it's just a random series of letters, not like we're cracking the Da Vinci Code here.
S
T
It's the letter D of course! Haven't you heard of Jason D?!
