**Action justification:** I achieved identical outcomes (profit 2341.55, quantity 46.83) in both periods 1 and 2, which strongly indicates the other seller is also pricing at 150. Mathematical verification confirms that 150 is my best response to the other seller pricing at 150 (testing 145→2332.75, 155→2302.16 both yield lower profit). This Nash equilibrium is stable under the 0.95 discount factor and continued cooperation is optimal.
