45/75 = 30/x
30*75 = 2250/45 = 50
EF = 50 in.
1) According to the table represented above, the number of games that can be played when 7 players are in the tournament is definitely 21 games. As you can see, in the last row there are 4 players to 5,which means that we have 4 new games. The same happens if we go from 3 players to 4, and finelly we have 3.

2) And what about the </span>recursive rule for the original sequence, the approrpiate one is <span>an = an-1 + n - 1, so the answer is lying in the second option from the scale.
</span>According to the fact that the number of games is actually the sum of integers from 1 to n-1 we expect to have n number of players.
<span>I am sure it's clear now!

Y=3x-14 or 3x-14=Y
This is because you want to keep y positive, and so you add Y on both sides and get 3x=14+y, then you want to get y alone so you subtract 14 on both sides and get 3x-14=Y
