Don't miss India's superhits!

the question is unclear but i will guess a series of matches in which each team has to play every other team once.

looking at some examples yields a pattern:

2 teams 1 game

3 teams 3 games (1 + 2)

4 teams 6 games (1+2+3) (1–2, 1–3, 1–4, 2–3, 2–4, 3–4)

5 teams 10 games (1+2+3+4)

so 15 teams would require (sum of the digits 1 thru 14)

a simple formula exists n(n+1)/2 14(14+1)/2 7 * 15 = 105 games
