Let the 4 lines be:
14, (91,961), 3
13, (161,692), 4
12, (251,443), 5
11, (361,214),6
Now add your line, which should be coherent with the logic of the 4 existing four lines.
From a spreadsheet of finite differences:
91961
161692 69731
251443 89751 20020
361214 109771 20020
491005 129791 20020 (italicized number added manually)
So next line is 10,(491,005),7
