.
For n = 1, 2, 3, 4 the sequence is -4, -5, -6, -7.


It is arithmetic progression with the first term -4 and the common difference of -1.


The general formula for the n-th term is 



     = -4 + (n-1)*(-1) = -4 - (n-1) = -4 - n + 1 = -3 - n,  n = 1, 2 , 3, 4 . . . 


ANSWER.   = -3 - n,  n = 1, 2, 3, 4, . . .
