Начало счета с не той цифры

Значение К должно начинаться с 1, начинается с 2. Как начать рассчет с 1?

void MAS()
{


for (x = 1; x <= 5; ++x)
{
k = 1;
do
{
++k;
numerator = pow(-1, k) * pow(x, 2 * k);
denominator = pow(k, x) * (k + 1) * (k + 2);
member = numerator / denominator;

if ((member < pow(10, 38)) && (abs(member) > pow(10, -38)))
{
sum += member;
out();
}
else
{
cout << "overflow float member - break cycle with k" << endl;
break;
}
} while (fabs(member) > accuracy);
cout << "==========================================" << endl;
}
}

C

void MAS()

{

    



      for (x = 1; x <= 5; ++x)

      {

          k = 1;

          do

             {

              ++k;

              numerator = pow(-1, k) * pow(x, 2 * k);

              denominator = pow(k, x) * (k + 1) * (k + 2);

              member = numerator / denominator;

              

              if ((member < pow(10, 38)) && (abs(member) > pow(10, -38)))

              {

                  sum += member;

                  out();                 

              }

              else

              {

                  cout << "overflow float member - break cycle with k" << endl;

                  break;

              }

             } while (fabs(member) > accuracy);

             cout << "==========================================" << endl;

      }

}
