The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones. The first 10 Fibonacci numbers are:
- 1
- 1
- 2
- 3
- 5
- 8
- 13
- 21
- 34
- 55
These numbers are derived by starting with 1 and 1, and then adding the last two numbers to get the next one. For example, 1 + 1 = 2, 1 + 2 = 3, 2 + 3 = 5, and so on.
