using namespace std;

int main() {
    int n;
    double k, sumPrice = 0;
    cin >> n >> k;
    vector<double>priceList(n + 1);

    for (int i = 0; i <= n; i++)

        cin >> priceList[i];
    }

    for (int i = n; i >= 0; i--)
    {
        sumPrice += priceList[i] / pow(1 + k, i);
    }

    cout << sumPrice;
    return 0;
