Math, microeconomics or criminal justice
a, ar, ar^2, ar^3, ar^4, ar^5 is the geometric sequence
a=-4, is the 1st term
ar^5 is the 6th term = (-4)(-1/3)^5 =4/243 or 4 divided by 3^5
each odd term is negative, each even term in the sequence is odd
each succeeding term is -r times the previous term
-4, 4/3, -4/9, 4/27, -4/81, 4/243, ...
