Explanation

The series is: 130, 225, 350, 520, 738, 1010. The pattern of differences is: 225-130=95, 350-225=125, 520-350=170, 738-520=218, 1010-738=272. The second differences are: 125-95=30, 170-125=45, 218-170=48, 272-218=54. These don't form a consistent pattern. The series may follow the pattern n³-5: 5³-5=120 (not 130), 6³+9=225, 7³+7=350, 8³+8=520, 9³+27=738, 10³+10=1010. The pattern is inconsistent but 225 breaks the expected flow more than others.
