 Create a function that returns a specific member of the Fibonacci sequence:
 
-> A series of numbers in which each number ( Fibonacci number ) is the sum of the two preceding numbers. The simplest is the series 1, 1, 2, 3, 5, 8, etc.
+> A series of numbers in which each number ( Fibonacci number ) is the sum of the two preceding numbers. The simplest is the series 0, 1, 1, 2, 3, 5, 8, etc.
 
 ```javascript
-fibonacci(4) // returns the 4th member of the series: 3  (1, 1, 2, 3)
-fibonacci(6) // returns 8
+fibonacci(4); // returns the 4th member of the series: 3  (1, 1, 2, 3)
+fibonacci(6); // returns 8
