Following a 5-0 reverse against Arsenal on Tuesday, which ended a three-game unbeaten run in all competitions, the young Foxes welcomed the Seagulls to Leicester last weekend.
However, they were two goals behind after 55 minutes, following Ben Wilson's penalty and a Laurent Tolaj strike, which both came after the half-time interval.
Johnson Gyamfi did narrow the arrears with 14 minutes to play, latching on to Terrell Pennant's assist, but City were unable to complete a stirring comeback in Premier League U18 South.
As a result, Leicester's youngsters are now seventh in the league, with 20 points from 15 matches, and just five behind fourth-placed West Ham United.
Last year, they were knocked out on penalties at Nottingham Forest in the fourth round, but have so far this season defeated Fulham, Crewe Alexandra and Bolton Wanderers. In 2014/15, though, an Under-18s squad including Ben Chilwell, Harvey Barnes and Hamza Choudhury overcame Wigan Athletic, Chesterfield, Southampton and Birmingham City to reach the semi-finals.
