We investigate the lepton flavor violation (LFV) decays, τ→ lγ (l=μ, e) and μ→ eγ, and the newly observed muon g-2 anomaly in the framwork of a squential fourth generation model with a heavy fourth neutrino, ν'. By using the recent experimental bounds, we take the constraints of the 4× 4 leptonic mixing matrix element factors, |V1ν' V2ν'|2, |V1ν' V3ν'|2 and |V3ν' V2ν'|2. We find that LFV decays and gμ-2 can exclude most of the parameter space of the 4th generation neutrino mass mν' and give stringent constraints on the existence of the fourth generation.
