The numbers could be
56 + 17 because Star was separating how she added the decimal places
She added the tens units first and then the ones units last.
so 50 + 10 first
and then 6 + 7
145,150,155,160,165,170,175. The pattern is that every time you get to a 0 in the ones digit, add a ten. When you get to a ten in the tens digits, add a thousand.
