✓
Answer
In magic square the numbers in each vertical, horizontal, and diagonal row add up to the same value. Sum of diagonal elements = 2 + 12 + 7 + 17 = 38 Now, Missing element in the first column = 38 - (2 + 9 + 14) = 38 - 25 = 13 Missing element in the first row = 38 - (2 + 15 + 16) = 38 - 33 = 5 Missing element in the second row and fourth column = 38 - (5 + 10 + 17) = 38 - 32 = 6 Missing element in the second row and third column = 38 - (9 + 12 + 6) = 38 - 27 = 11 Missing element in the fourth row and third column = 38 - (16 + 11 + 7) = 38 - 34 = 4 Missing element in the third row and third column = 38 - (13 + 7 + 10) = 38 - 30 = 8 Missing element in the fourth row and second column = 38 - (14 + 4 + 17) = 38 - 35 = 3 Hence, the complete magic square is
