Please help me find the next three numbers in this geometric sequence

Please help me find the next three numbers in this geometric sequence

625,225,75...  

and please explain how you got that answer so i can understand.

A geometric  sequence has the same factor  between each number. Not here !

$\frac{625}{225} = 2.77777777778 \\ \frac{225}{75} = 3 \\ 2.77777777778 \ne 3$

maybe 755/355

625 plus 130 = 755

225 plus 130 = 335
