Given is the arithmetic-geometric sequence u(k) = (900-3k)rk-1.

Let s(n) = Σk=1...nu(k).

Find the value of r for which s(5000) = -600,000,000,000.

Give your answer rounded to 12 places behind the decimal point.

--hints--

euler235() should return 1.002322108633.

assert.strictEqual(euler235(), 1.002322108633);

function euler235() {

  return true;
}

euler235();
