Write the correct number in the given boxes from the following A.P.: (i) 1, 8, 15, 22, . . . (ii) 3, 6, 9, 12, . . . (iii) -3, -8, -13, -18, . . . (iv) 70, 60, 50, 40, . . .

Write the correct number in the given boxes from the following A. P.

(i) 1, 8, 15, 22, ... Here \(a = \square, t_1 = \square, t_2 = \square, t_3 = \square\); \(t_2 - t_1 = \square - \square = \square\); \(t_3 - t_2 = \square - \square = \square\) ∴ \(d = \square\)

(ii) 3, 6, 9, 12, ... Here \(t_1 = \square, t_2 = \square, t_3 = \square, t_4 = \square\); \(t_2 - t_1 = \square\), \(t_3 - t_2 = \square\) ∴ \(d = \square\)

(iii) −3, −8, −13, −18, ... Here \(t_3 = \square, t_2 = \square, t_4 = \square, t_1 = \square\); \(t_2 - t_1 = \square\), \(t_3 - t_2 = \square\) ∴ \(a = \square\), \(d = \square\)

(iv) 70, 60, 50, 40, ... Here \(t_1 = \square, t_2 = \square, t_3 = \square\), ... ∴ \(a = \square\), \(d = \square\)
