Question

32 teams enter for a knockout competition, in which each match results in 1 team winning and the other team losing. After each match the winning team goes on to the next round, and the losing team takes no further part in the competition. Thus 16 teams play in the second round, 8 teams play in the third round, and so on, until 2 teams play in the final round.

How many teams play in only 1 match?

Answer 1

This is considered a single-elimination tournament. Only teams that win proceed to the next game.

Once you lose, you're out.

I created a bracket with 32 teams and they've all played in the first round.
How many teams will proceed to the next round? These teams will be playing more than one game.

How many teams lost in the first round?
These are the teams that will only play one game and will not play any more games because they're out.

Answer 2

There are 32 teams so there is going to be 16 games in the first round.

Each game has a winner and a loser.
