Question

what is the approximate value of $phi$ (the golden ratio)?
a. 1.618
b. 2.718
c. 1.500
d. 1.414

Explanation:

The Golden Ratio, denoted by $\phi$, is calculated as $\frac{1 + \sqrt{5}}{2}$.
Calculating $\sqrt{5}\approx2.236$, then $1+\sqrt{5}\approx3.236$.
Dividing by 2 gives $\frac{3.236}{2}=1.618$.

Answer:

A. 1.618
