Are you sure such formula exists? Even The On-Line Encyclopedia of Integer Sequences does not have it or its simplified version:
# - #[[1]] &@{105208, 105508, 105637, 105934, 106208, 106258, 106377, 106769, 107293, 107537}
{0, 300, 429, 726, 1000, 1050, 1169, 1561, 2085, 2329}
Explaining what is the nature of the numbers, giving more numbers, and any additional information - desirably complete info about the problem - would be helpful.
