Answer» Write the correct number in the given boxes from the following A. P. (i) 1, 8, 15, 22,... Here a = , t1 = , t2 = , t3 = , t2 – t1 = – = t3 – t2 = – = ∴ d = (ii) 3, 6, 9, 12,... Here t1 = , t2 = , t3 = , t4 = , t2 – t1 = , t3 – t2 = ∴ d = (iii) –3, –8, –13, –18,... Here t3 = , t2 = , t4 = , t1 = , t2 – t1 = , t3 – t2 = ∴ a = , d = (iv) 70, 60, 50, 40,... Here t1 = , t2 = , t3 = ,... ∴ a = , d = |
