Which of the following are APs? If they form an AP, find the common difference \(d\) and write three more terms. (i) 2, 4, 8, 16, \ldots (ii) 2, \(\frac{5}{2}, \frac{3}{2}, \frac{7}{2}, \ldots\) (iii) -1.2, -3.2, -5.2, -7.2, \ldots (iv) -10, -6, -2, 2, \ldots (v) 3, 3 + \sqrt{2}, 3 + 2\sqrt{2}, 3 + 3\sqrt{2}, \ldots (vi) 0.2, 0.22, 0.222, 0.2222, \ldots (vii) 0, -4, -8, -12, \ldots (viii) \(-\frac{1}{2}, -\frac{1}{2}, -\frac{1}{2}, -\frac{1}{2}, \ldots\)
