    My solution to the problem is as follows:

    F (x) = 4x - 6

    when x = 1, F (x) = 4 * 1 - 6 = - 2

    when x = 2, F (x) = 4 * 2 - 6 = 2

    when x = 3, F (x) = 4 * 3 - 6 = 6

    when x = 4, F (x) = 4 * 4 - 6 = 10

    The second row is: - 2, 2, 6, 10

    The differences are: 2 - (-2) = 4; 6 - 2 = 4; 10 - 6 = 4

    The differences are the same and equal to 4.

    Therefore, the second row is in arithmetic progression.

    So it is True.
