The spiral patterns on pine cones and cycads, the number of petals on certain flowers, the number of leaves on the stems of some plants, and the arrangement of seeds on a sunflower seed head are some examples of Fibonacci sequences.
The number of sequences is 27 or 128.
Add a constant number to one term to find the next term
There are infinitely many possible number sequences, and infinitely many numbers which can appear in those sequences. Any and every number can appear in a number sequence.

All types of maths appear in nature; circles that appear in nature gave rise to the number "pi", exponential sequences in nature gave rise to the number 'e', trigonometric functions model curves, probabilities can be calculated for naturally occurring "events", Mandelbrots' sequences model trees, snowflakes etc... Differential equations can be used to model flow rates, cell division (and cancer proliferation), growth etc... When you look for it, maths is pretty much the basis of everything.
Yes.

A few examples: Counting numbers are an arithmetic sequence. Radioactive decay, (uncontrolled) bacterial growth follow geometric sequences. The Fibonacci sequence is widespread in nature.
Could it be check Digits?
The answer depends on the exact nature of the puzzle.
1123581321, this is one of the most famous number sequences in the world; the reason being is that ; the first two numers add up to the 3rd, the 3rd and 4th number add up to the 5th etc.
It's not used anywhere by people. But it's used by Nature, wherever plants grow.
