The number of teams remaining after each round can be calculated by halving the previous round's number of teams.
After the first round, half of 128 teams are eliminated, leaving 64 teams.
After the second round, half of 64 teams are eliminated, leaving 32 teams.
After the third round, half of 32 teams are eliminated, leaving 16 teams.
After the fourth round, half of 16 teams are eliminated, leaving 8 teams.
After the fifth round, half of 8 teams are eliminated, leaving 4 teams.
Therefore, there will be 4 teams left after 5 rounds.
