Question
Study the given pattern carefully and select the number
that can replace the question mark [?] in it.First row: 10, 6, 964 Second row: 7, 3, 334Third row: 5, 2, [?] (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: 10³ - 6² = 1000 - 36 = 964
Second row: 7³ - 3² = 343 - 9 = 334
Third row: 5³ - 2² = 125 - 4 = 121
