While training on final radar Aircraft X was being vectored for sequence to the runway.  The aircraft was descended below the normal downwind altitude to avoid traffic in an adjacent sector airspace.  Due to traffic volume and complexity; the aircraft was vectored into a 6;000 foot Minimum Vectoring Altitude (MVA).  Upon realization of the error; he was immediately climbed and turned away from the higher MVA area.
A11 TRACON Controller conducting on the job training reported the trainee vectored an aircraft for sequencing below the Minimum Vectoring Altitude.
