Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row- 2, 57, 7
Second row- 6, 225, 3
Third row- 5, ?, 2
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 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)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 129
Logic: In each row, the second number is the sum of the Cube of the first number and the square of the second number.
First row- 2, 57, 7: 23 + 72 = 8 + 49 = 57
Second row- 6, 225, 3: 63 + 32 = 216 + 9 = 225
Similarly,
Third row- 5, ?, 2 = 53 + 22 = 125 + 4 = 129
Hence, the correct answer is 129.
