Özet
In this paper we investigate the Lambda-CDM universe by selecting the specific time dependent form of Lambda, viz. (Lambda) over dot proportional to H(3), in the context of 5- dimensional space time. Time-dependent form of equation of state parameter w is derived along with a possible signature flip of deceleration parameter q. It is also observed that a present age of the Universe, calculated for some specific values of parameter agrees very well with the observational data.
