In the present paper, we treat an infinite series $(\alpha,\beta)$-metric $L=\beta^2/(\beta-\alpha)$. First, we find the conditions that a Finsler metric $F^n$ with the metric above be a Berwald space, a Douglas space, and a projectively flat Finsler space, respectively. Next, we investigate the condition that a two-dimensional Finsler space with the metric above be a Landsbeg space. Then the differential equations of the geodesics are also discussed.
Keywords: Berwald space, Douglas space, differential equations of geodesics, Finsler space, $(\alpha,\beta)$-metric, Landsberg space, projectively flat
