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.
