    Question

    A number series is given below,

    which follows a specific pattern. If 'A' represents the 'x'th term and 'B' represents the '(x + 1)th term, determine the correct relationship between 'A' and 'B'. Series: 8, 25, 76, 229, 688
    A B = 2A - 1 Correct Answer Incorrect Answer
    B B = 3A Correct Answer Incorrect Answer
    C B = 3A + 1 Correct Answer Incorrect Answer
    D B = A - 1 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Logic in the series is: (8 × 3) + 1 = 25 (25 × 3) + 1 = 76 (76 × 3) + 1 = 229 (229 × 3) + 1 = 688 Hence, B = 3A + 1
