Explanation

This option is correct because the given series is based on the following pattern: 280 + 75 = 355 355 + (75 + 1 x 7 = 82) = 437 437 + (75 + 2 x 7 = 89) = 526 526 + (75 + 3 x 7 = 96) = 622 622 + (75 + 4 x 7 = 103) = 725 ? = 725 + (75 + 5 x 7 = 110) = 835 Hence, 835 will replace the question mark.
