At 300 K, The gases in order of increasing average velocity will be N2O < Ar < N2 < CH4

The molecular mass of of a gas is directly proportional to its Molecular Velocity. That is to say that  Gases made up  lighter molecules will have greater  high-speed particles and relatively higher velocities while . Gases made up of heavier molecules have greater  low-speed particles, and  relatively lower velocities.

Therefore  considering the gases

  • N20 with 44.013 g/mol ,
  • Ar with 39.948g/mol
  • N2  with 28.0134 g/mol
  • CH4 with  16.04 g/mol

The order of increasing average velocity at 300K will be N2O < Ar < N2 < CH4
