Explanation:

Step1: Identify the pattern (multiples of 2)

The row for 2: \(2\times1 = 2\), \(2\times2 = 4\), so the pattern is \(2\times n\) where \(n\) is the column number (1 - 10).

Step2: Calculate for column 3

For column 3 (n=3): \(2\times3 = 6\).

Step3: Calculate for column 5

For column 5 (n=5): \(2\times5 = 10\).

Step4: Calculate for column 6

For column 6 (n=6): \(2\times6 = 12\).

Step5: Calculate for column 7

For column 7 (n=7): \(2\times7 = 14\).

Step6: Calculate for column 9

For column 9 (n=9): \(2\times9 = 18\).

Step7: Calculate for column 10

For column 10 (n=10): \(2\times10 = 20\).

Answer:

The filled sequence for row 2 (from column 3 to 10) is: 6, 10, 12, 14, 18, 20 (so the squares are 6 (column 3), 10 (column 5), 12 (column 6), 14 (column 7), 18 (column 9), 20 (column 10)).
