A wonderfully satisfying sci-fi short read! I admire when form intertwines with the narrative function of a story. Or, put another way, when the type of story being told is considered in the choice of writing style. 

Asimov proves he understands the magic of this method in his drafting of The Last Question.

In crafting a creation myth, he utilizes repetitious language and numbered sequential time intervals, intentionally mimicking the form of the biblical Genesis account.

Because of this, I was able to guess at the story's ending, and hoped this was what Asimov was playing at, long before reaching the final sentence of the story. 

As is true of the best speculative fiction, The Last Question leaves the reader with a delectable sense of  "what if?".
