Sorry to say, but Seviper doesn't evolve, ever, in any Pokemon game.
I think you would get an F if you were quizzed on Pokémon. Why do you think it evolves into Seviper? Arbok does not evolve, and Seviper is just a whole different Pokémon. It's ok if you were confused because Jessie used to have an Arbok and she gave it up and got Seviper, and you thought that her Arbok had just evolved. Hope I helped! :)
Seviper can be found in Route 114, which is south-west of Fallarbor Town. It is not accessible in Poke'mon Ruby, by the way.
