m? Are you studying "Mary Had a Little Lamb"? Math? What This looks like math, but I can't know unless you abandon text-speak code and use English.
c'mon -- just start plugging in values for n:
n=1: 1(1-2)-3 = -4
n=2: 2(2-2)-3 = -3
n=3: 3(3-2)-3 = ...

n=2: 2(2-2)-3 = -3
n=3: 3(3-2)-3 = ...
and so on
