WebIn the AP, a = -8. The ratio of the 7th and the 9th terms is a+6d : a+8d = 5:8, or 8 (a+6d) = 5 (a+8d) or 8a + 48d = 5a + 40d, or 48d-40d = 5a-8a 8d = -3a, or d = -3a/8 = (-3)* (-8)/8 = 3. The common difference is 3. And the AP is -8, -5, -2, 1, 4, 7, 10, 13, 16 The 7th term is 10 and the 9th term is 16 and their ratio is 10:16 or 5:8.
