The letter that directly precedes the letter "N" in the English alphabet is the letter "M". The letter "M" is the 13th letter of the alphabet, while "N" is the 14th letter. Directly following the letter "N" is the vowel "O". The letter "O" is also a vowel, and is the 15th letter of the alphabet. It is the 4th vowel in the alphabet.
The letter M
what comes after g
the letter E
as the first letter of the greek alphabet, "alpha" comes first.
The letter 'B' comes after 'A'.
Here is the pattern. It begins with the first letter of the alphabet and then "adds" five letters. The next letter comes from the end of the alpahabet and "subtracts" five letters. The fifth in the series (G) adds one off from the second (F). If one adds five to that the sixth in the series (L) comes next. We then move to the letter before "U" to get the seventh in the series. To sum it all: We added five to get from the A to F and G to L. We subtracted five to get from Z to U. To answer the question, we subtract five from T to get O I think!
I would say following the letter address, space two lines for the date, then another two lines for a reference (if applicable) then two lines following that comes the saluation. Between the letter address and the saluation, I would say at least four lines
