Fibonacci numbers have always been around. Many scholars believe the concept was first noticed by mathematicians of India. Leonardo of Pisa (known as Fibonacci) first introduced the sequence to Western European mathematics in a 1202 book entitled LiberAbici, thus the sequence bears his name.

the fibonacci pattern of numbers came round about in the 1980's
A Fibonacci number, Fibonacci sequence or Fibonacci series are a mathematical term which follow a integer sequence. The first two numbers in Fibonacci sequence start with a 0 and 1 and each subsequent number is the sum of the previous two.
The 9th number in the Fibonacci Sequence is 34, and the 10th number in the Fibonacci sequence is 89.
4 Fibanocci numbers are each the sum of the 2 previous numbers, i.e. 1,1,2,3,5,8 Thus 4 is the first one missing By modern definition, the above response is incorrect - 0 (zero) is both positive (it is defined as such) and not in the Fibonacci set. This answer is given based on a slight assumption, there cannot be a "first number" on a number line. The lowest number that is positive and not within the set of Fibonacci numbers (as inferred as the true meaning of your question) is zero.
No.
Fibonacci numbers appear in many natural contexts. Try the link below for a taste: it also gives a list of references if you wish to follow.

the first seven Fibonacci numbers are 1,1,2,3,5,8,13. 13 is a Fibonacci number.
Leonardo Fibonacci first recorded his sequence in his book Liber Abaci, which was published in 1202.

They will always follow some Fibonacci sequence. If P and Q are any two numbers, then they belong to the Fibonacci sequence with the first two numbers as P and (Q-P).
The first 11 Fibonacci numbers are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and 55.
He was not the first to discover it. Fibonacci lived around 1200 AD. He might have discovered it independently but it was known in India from 200 BC.
