The problem is a bit underspecified, perhaps. 'n' is a positive integer, so 1, 2, 3, .... So the sequence is found by multiplying 1504170715041707 by 1, 2, 3,

The problem is a bit underspecified, perhaps. 'n' is a positive integer, so 1, 2, 3, .... So the sequence is found by multiplying 1504170715041707 by 1, 2, 3, ... sequentially, then finding the remainder when you divide each of those products by 4503599627370517.
