OpenStudy (lgbasallote):

200

if u want one more number, after 855 comes 1729 this should ring a bell.

OpenStudy (mathmate):

The best hint is from 1729, the taxi number.

OpenStudy (lgbasallote):

hartnn (hartnn):

OpenStudy (mathmate):

I have miscalculated 7^3+8^3 as 755 so missed it. :(

OpenStudy (mathmate):
