    Step-by-step explanation:

    (a)

    Note the squared value in column 3 which is the square of 1 more than the row number, that is

    row 2 → (2 + 1)² →3²

    row 3 → (3 + 1)² → 4²

    Find the square root of 676 = 26 → (25 + 1)² = 26²

    Hence the row number is 25

    (b)

    The pattern in column 1 is [ row number × (row number + 2 ) + 1 ]

    row number is n then n(n + 2) + 1 = n² + 2n + 1
