Assuming Language required C it will not compute 15 no you can define how many no you want to compute for
#include<stdio.h>
void main()
{
int n,new,i;
int a[2]={0,1};
printf("Enter the no up to where you want to find the series\n");
scanf("%d",&n);
printf(" Fibonacci series\n0\n1\n");
for(i=3;i<=n;i++)
{
new=a[0]+a[1];
printf("%d\n",new);
a[0]=a[1];
a[1]=new;
}
}
