help.

now tell how u arrive at this formula?

Oops. Sorry. The correct formula is n*(n+2)*(2*n+1)/8.

You
i've modified my algorithm
but i'm getting wrong answer. someone help..
#includeiostream
using namespace std;
unsigned long long start,end,arr[101],arr2[101];
int main(){
int j,t,i,n;
for(i=0;i100;i++){
arr[i]=i+1+arr[i-1];
}
for(i=0;i100;i++)
{
arr[i]+=arr[i-1];
}
arr2[1]=1;
Isn't the number of triangles in level n just n*(n^2 + 6 n - 1)/6?
