The first terms should be:

1100090011, 1100900011, 1103093011, 1103903011, 1154094511,
1154904511, 1213093121, 1213903121, 1304094031, 1304904031,
1364094631, 1364904631, 1367097631, 1367907631, 1421091241,
1421901241, 1450090541, 1450900541, 1466096641, 1466906641,
1495095941, 1495905941, 1498098941, 1498908941

In these terms all the difference are equal to 30^4.
