The answer is true, and let me explain this to you like this: <span>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 </span><span>second row is: -2, 2, 6, 10 </span><span>differences are: 2 - (-2) = 4; 6 - 2 = 4; 10 - 6 = 4 </span>So, the <span>second row is in arithmetic progression. Hope this is what you were looking for</span>
