Guardians of the Asgard

We are the protectors of Asgard planet. Thor have provided us with a mighty number $n$ , which is to be used to obtain a sequence of natural numbers. The sequence of numbers is the key to the survival of the planet. Can you find the sequence with the help of the following information? $$ The sequence is $a_{0} , a_{1} . . . . . . , a_{k}$ , where $a_{0} = 1$ and number of elements in sequence is minimum possible $\sum a_{i} = n$ $a_{i} \leqslant a_{i+1} \leqslant 2a_{i}$ k is minimum possible. $$ We are assigned the task to find the number of terms in the sequence (we've to find k+1) when $n = 981241785$ . $$ Bonus : find all elements of the sequence $$ Inspiration : code-forces
