Let's see... a sequence of positive even integer values, interspersed with
the negative of the intervening odd integers...

>>> for i in range(50):
... 	j = 2 * (i + 1)
... 	print j, -(j + 1),
... 	
2 -3 4 -5 6 -7 8 -9 10 -11 12 -13 14 -15 16 -17 18 -19 20 -21 22 -23 24 -25
26 -27 28 -29 30 -31 32 -33 34 -35 36 -37 38 -39 40 -41 42 -43 44 -45 46
