Greetings from ???

Upon seeing this series of numbers, Benjamin was slightly dumbfounded.

What was this?

Was it like those logical reasoning test where you were asked to fill in the next number by understanding the pattern of the series? Or was it some encrypted code which was used to deliver message from extraterrestrial beings to Earthlings through natural phenomenon?

This did not seem right. Wasn’t this a fantasy or magic genre kind of story? Why a mathematics question out of the blue?

But, Benjamin did not dare to take it lightly. He knew that this series of numbers might very likely hide the secrets of that world. Thus, upon seeing this series of numbers, he spent nearly an hour to study it.

Unfortunately, he could not figure anything out.
