    I. e., 2, 7 = 65 is inter-related with 3, 4 = 130 and 6, 9 = 233 is inter-related with 5, 8 = ..??

    We know that by formula __
    (a+b)² = a ² + b ² + 2ab
    Can we written as___

    2, 7 = (2 + 7)² + 7² = 81 + 49 = 130 = 3, 4
    And____
    3, 4 = (3 + 4)² + 4² = 49 + 16 = 65 = 2, 7
    Likewise,
    5, 8 = (5 + 8)² + 8² = 169 + 64 = 233 = 6, 9
    And__
    6, 9 = (6 + 9)² + 9² = 225 + 81 = 306 = 5, 8

    ∴ 306 is the right answer
