Call the first one x. The next one is x+2...so that when all four are added you get
x + x+2 + x+4 + x+6 = -72
4x + 12 = -72
4x = -84
x = -21
So the numbers are -21, -19, -17, -15.

Let the numbers be:
+n+, +n+%2B+2+, +n+%2B+4+, +n+%2B+6+
---------------------
given:
+n+%2B+n+%2B+2+%2B+n+%2B+4+%2B+n+%2B+6+=+-72+
+4n+%2B+12+=+-72+
+4n+=+-84+
+n+=+-21+
+n+%2B+2+=+-19+
+n+%2B+4+=-17+
+n+%2B+6+=+-15+
-----------------
The consectutive odd integers are:
-21, -19, -17, and -15
----------------------
check:
+-21+-19+-17+-15+=+-72+
+-72+=+-72+
OK
