Yes, the most common one is the sunflower.
If you start with 1, the common factors are 1 and 3. If you start with zero, as Fibonacci did, the common factor is 1.
The ratio of dividing the larger Fibonacci number into the smaller Fibonacci number gives you the golden ratio (1.618 to 1). -------- The Golden Ratio is the number (1+sqrt(5))/2~=1.618 The Fibonacci sequence is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... . Skipping the first two terms, if you divide one term in this sequence by the previous term the resulting sequence converges to the Golden Ratio: 1.0000 2.0000 1.5000 1.6667 1.6000 1.6250 1.6154 1.6190 1.6176 1.6182 1.6180 Please see the link for more information.
Oh, dude, Leonardo Fibonacci totally tied the knot! Yeah, he got married to a lovely lady and probably had a super fun wedding with some Fibonacci sequence-inspired decorations. Like, can you imagine the seating chart following that sequence? Hilarious!
Different authors use different conventions for indexing the Fibonacci sequence (n.b., "sequence" not "series"). For example, in Cameron's Combinatorics, he defines F1=1, F2=2. The most common choice, used for example in Sloane's Online Encyclopedia of Integer Sequences (http://www.research.att.com/~njas/sequences/), is to define thezeroth Fibonacci number to be 0 and the first to be 1; thus the second is also 1. With this choice, a number of formulas become simpler and we have this particularly nice number-theoretic result: if m divides n, then the mth Fibonacci number divides the nth Fibonacci number.
There may be other patterns: For example: 1,3,9,27, ... is multiplicative and has a common multiple of 3; 1,4,9,16, ... are the squares of integers; 1,1,2,3,5,8, ... is the Fibonacci sequence where each number after (the first two) is the sum of the previous two elements. 1,3,7,13,21, ... is generated by t(n) = n2 - n + 1 and so on. The choices are endless.

No. An 'arithmetic' sequence is defined as one with a common difference.A sequence with a common ratio is a geometricone.
The Fibonacci sequence, where each number is the sum of the two preceding ones, is a common occurrence in nature. This sequence can be seen in the branching of trees, the arrangement of leaves, and the spiral patterns of shells and flowers.
the answer is 4
The sequence is neither arithmetic nor geometric.
