Question
Fibonacci series is a set of numbers where the next number is the sum of the previous 2.
So if the first number is 0 and second number is 1, the next number number will be 0+1 = 1 and the series will be 0,1,1
The next number will be 1+1 = 2 and the series will be 0,1,1,2 and the next will be 2+1 = 3 making the series 0,1,1,2,3. The next one being 3+2 = 5 then 5+3 = 8 and so forth.
For this assignment write a Fibonacci series for the first 10 numbers using JavaScript. The first two seed numbers will be 0 and 1.
Print the first 13 number of the series
0 1 1 2 3 5 8 13 21 34 55 89 144.
Load the series on body load. This means you will need to have you body tag as <body>
You will need to write your function. Print the first two seed numbers outside your for loop using
document.writeln(number1);
document.writeln(number2);
After this inside your function you will need to create a for loop that will contain the rest of the series.

<scriptlanguage>="JavaScript"
function yourFunctionName() {
var number1, number2, number3,n;
n=parseInt(prompt("Enter number"));
number1=0;
number2=1;
document.writeln(number1);
document.writeln(number2);
for(var i=3;i<=n;i++) {
number3=(number1+number2);
document.writeln(number3);
number1=number2;
number2=number3;
}
}
