How do you find the nth term (edit) which have say the fifth term ascending instead of descending

e.g.

-576; -1025, -1728, -2816, -2241

Answer this: how do you find the 3rd term -1728?

Look up "arithmetic sequences" and "geometric sequences".

Where did the numbers come from? Is it known why the third is three times the first?

Repeating Skipjack's question: WHERE did the numbers come from?

WHAT do they represent?
The month to month reduction of the rat population in Timbuktu?
