    that can replace the question mark [?] in it. First row: 6, 5, 191 Second row: 9, 7, 680 Third row: 4, 5, [?] (NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits.

    Solution

    The logic followed here is as follows: Third number = (First number)³ - (Second number)² First row: 6³ - 5² = 216 - 25 = 191 Second row: 9³ - 7² = 729 - 49 = 680 Third row: 4³ - 5² = 64 - 25 = 39
