What is the golden ratio of 8?

Published in Golden Ratio 2 mins read

The concept of "the golden ratio of 8" is not directly applicable in the way the question might imply. The golden ratio (approximately 1.618) is a mathematical constant, often denoted by the Greek letter phi (φ). While 8 itself does not have a golden ratio, we can explore how the golden ratio relates to the number 8, primarily through the Fibonacci sequence.

The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones (e.g., 0, 1, 1, 2, 3, 5, 8, 13, 21...). A key property is that as the sequence progresses, the ratio between consecutive Fibonacci numbers approaches the golden ratio.

Let's consider Fibonacci numbers near 8:

Fibonacci Number Divided by the Previous One Result
5 N/A N/A
8 8/5 1.6000
13 13/8 1.6250
21 21/13 1.6154...
34 34/21 1.6190...

As you can see, dividing a Fibonacci number by its predecessor gives a ratio that gets closer to the golden ratio as the numbers get larger. The ratio of 13/8 = 1.625 is an approximation of the golden ratio using the Fibonacci number 8 and its successor.

Therefore, if the question intends to explore the golden ratio in the context of the Fibonacci sequence around the number 8, then the relevant ratios (13/8 = 1.625 or 8/5 = 1.6) provide an approximate connection. However, it's important to clarify that 8 itself doesn't have a golden ratio in isolation. The golden ratio emerges as a limit in the ratios of consecutive Fibonacci numbers.
