The spirals on this sunflower follow what number sequence?
A Fibonacci sequence
B Riemann zeta function
C Bernoulli numbers
The gorgeous sunflower displays its seeds in two spirals that twist and curve in opposite directions. If you mapped either of those spirals on a graph, they would closely follow the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21…).
Sunflowers are not only pretty and a good math lesson—they’re tall! Guinness World Records lists the tallest sunflower at 30 feet 1 inch, grown in Germany by Hans-Peter Schiffer. (The average sunflower reaches from 5 to 10 feet, though there are giant and dwarf varieties too.)
The correct answer is Fibonacci sequence.
