Another golden ratio expression

I made another golden ratio expression.  This is the sixth golden ratio equation and the third in "Rational number series " or "3 consecutive numbers and 4 consecutive numbers " theory. 3 is a powerful number.  Because I got 3 golden ratio expressions with "Rational  number series " or "3 consecutive numbers and 4 consecutive numbers " theory; my theory gets acceptance.

The equation is

Putting y as -2/3 or -0.666666. .  gives n as phi or the golden ratio. 

How about that? Evil changes to God by my equation!!
