The image is really unclear but I will assume that the number of teams given = 66
and the formula is

plug in the number of teams

multiply both sides by two

subtract 132 from both sides and factor
t = 12
6x - 12 = 8x + 14
2x = - 26
x = - 13
For this, let's have:
n represent each number, the number after it is its place in sequence
/ means divide
n1 /2 = n2, etc.
