Which of the following recursive formulas represents the same arithmetic sequence as the explicit formula an = 2 + (n – 1)5?

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
