Is this supposed to be m%5Bn%5D+=+%281%2F2%29%2A%28m%5Bn-1%5D-1%29?
m%5B1%5D+=+13
m%5B2%5D+=+%281%2F2%29%2A%28m%5B1%5D-1%29+=+%281%2F2%29%2A%2813-1%29+=+6
m%5B3%5D+=+%281%2F2%29%2A%28m%5B2%5D-1%29+=+%281%2F2%29%2A%286-1%29+=+5%2F2
m%5B4%5D+=+%281%2F2%29%2A%28m%5B3%5D-1%29+=+%281%2F2%29%2A%285%2F2-1%29+=+3%2F4
m%5B5%5D+=+%281%2F2%29%2A%28m%5B4%5D-1%29+=+%281%2F2%29%2A%283%2F4-1%29+=+-1%2F8
In general,the general formula would be m%5Bn%5D+=+14%2F2%5E%28n-1%29+-1 for n = 1, 2, 3, 4, 5,...
