Which term of the A.P. 27, 24, 21, 18, ...... is the first negative term ? 1. 10th 2. 11th 3. 12th 4. 9th

Let nth term of the A.P. be the first negative term. Given, A.P. = 27, 24, 21, 18, ...... First term (a) = 27 and common difference (d) = 24 - 27 = -3. By formula, a n = a + (n - 1)d Since, nth term is less than zero. ∴ a + (n - 1)d 0 ⇒ 27 + (n - 1)(-3) 0 ⇒ 27 - 3n + 3 0 ⇒ 3n 30 ⇒ n ⇒ n 10. So, n = 11. Hence, Option 2 is the correct option.
