Find a three−digits number whose  digits form a geometry progression  ;if you known that after substract that  number by 495 ,get a number  written by the same digits as the  number you are looking for but in the  reverse order;if the digits of the  number obtained after  substraction(from left right)reduced  by 1,1 and 2 respectively ,you obtain  an arithmetic progression
