Question
Study the given pattern carefully and select the number
that can replace the question mark [?] in it.First row: 6, 5, 191Second row: 8, 7, 463Third row: 9, 10, [?] (NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 13 - Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)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: 8³ - 7² = 512 - 49 = 463
Third row: 9³ - 10² = 729 - 100 = 629
