There is very little information in the question to go on, but it looks like the next letter is R - an interval of five letters.
w
It looks as if every third letter is an "r"; the remaining letters are in sequence.
T then V There are five letters between B and H, four between that and M, then three, then two...
M and N
T
the next letter would be 'b'
it's very simple, i think you didnt think at all :) it is letter S
y
N for november. The sequence starts with march.
The next letter in the sequence is M. The sequence follows the alphabetical order with a pattern of skipping letters.
n for November
As I interpreted it, the sequence is the first letter of 4 months in chronological order, January February March April So therefore the next letter would be M for May.
