First term, a, is 486.  

But I don't view this as a geometric series.  For it to be such a series, you must be able to find a common ratio, r, which multiplies each term to obtain the next term.  726 is 1.494 times 486.  Unfortunately, 728 is NOT 1.494 times 726.

Please ensure that you have copied this problem down accurately.  Thx
