The numbers 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000 are the start of an interesting sequence.

Now
* 2FD1 divided by 27 gives 1876.037037…. - that doesn’t look promising.
* 2FD1 multiplied by 27 is 1 367 631 – that looks even worse.
* How is 27 involved in the above numbers?
Have fun working through the options.
