A Correct answer
Explanation

The pattern is dividing by decreasing numbers: 6720/1.33≈5040, 5040/1.25=4032, 4032/1.2=3360, 3360/1.167≈2880, 2880/1.143≈2520 (not 2525). The expected value after 2880 should be approximately 2520, but we have 2525 which doesn't fit the division pattern. Alternatively, checking: 6720-1680=5040, 5040-1008=4032, 4032-672=3360, 3360-480=2880, 2880-355=2525. The decrements are: 1680, 1008, 672, 480, 355. These don't show a clear pattern, but 2525 breaks the expected value.
