--description--

Data la sequenza aritmetico-geometrica u(k) = (900 - 3k)r^{k - 1}.

Sia s(n) = \sum_{k=1 \ldots n} u(k).

Trova il valore di r per il quale s(5000) = -600\\,000\\,000\\,000.

Dai la tua risposta arrotondata a 12 cifre dopo il punto decimale.

--hints--

arithmeticGeometricSequence() dovrebbe restituire 1.002322108633.

assert.strictEqual(arithmeticGeometricSequence(), 1.002322108633);

--seed--

--seed-contents--

function arithmeticGeometricSequence() {

  return true;
