The answer is 93 

If we sorted out the number of each hours, the sequence will look like this

57 _    69  _  81  _ x  _ 105   

(in which x is the fourth hour of work)


We can see from the sequence that each hours, the mailman add additional 12 letters.
(69 - 57 = 12)
(81 - 69 = 12)   . . . . proof


So, the amount of letters on the fourth hour would be:
81 letters  + 12 letters = 93 Letters
