# --description--
|
||||
|
||||
For any positive integer n the function next_prime(n) returns the smallest prime p such that p>n.
|
||||
|
||||
The sequence a(n) is defined by: a(1)=next_prime(1014) and a(n)=next_prime(a(n-1)) for n>1.
|
||||
|
||||
The fibonacci sequence f(n) is defined by: f(0)=0, f(1)=1 and f(n)=f(n-1)+f(n-2) for n>1.
|
||||
|
||||
The sequence b(n) is defined as f(a(n)).
|
||||
|
||||
Find ∑b(n) for 1≤n≤100 000. Give your answer mod 1234567891011.

`euler304()` should return 283988410192.
|
||||
|
||||
```js
|
||||
assert.strictEqual(euler304(), 283988410192);
