    B 613 Correct Answer Incorrect Answer
    C 703 Correct Answer Incorrect Answer
    D 812 Correct Answer Incorrect Answer

    Solution

    The logic followed in the given series is: 1st term x (1st term – 3rd term) = 2nd term   First row: 26, 312, 14 26 x (26 – 14) = 312 26 x 12 = 312 312 = 312 Second row: 55, 1705, 24 55 x (55 – 24) = 1705 55 x 31 = 1705 1705 = 1705 Third row: 37, ?, 18 37 x (37 – 18) = ? 37 x 19 = ? ? = 703   Hence, the correct answer is (C).
