# --description--
|
||
|
||
给定是算术几何序列u（k）=（900-3k）rk-1。设s（n）=Σk= 1 ... nu（k）。
|
||
|
||
找到r的值，其中s（5000）= - 600,000,000,000。
|
||
|
||
将您的答案四舍五入到小数点后面的12位。
|
||
|

# --hints--
|
||
|
||
`euler235()`应该返回1.002322108633。
|
||
|
||
```js
|
||
assert.strictEqual(euler235(), 1.002322108633);
|
||
```
|

```js
|
||
function euler235() {
|
||
|
||
return true;
|
||
}
|
||
|
||
euler235();
|
