If 9 term of an ap is zero
Web15 apr. 2024 · Let a be the first term and d be the common difference of an AP. a4 = a + (n- 1)d = a + (4 – 1)d = a + 3d Since 4th term of an AP is zero. a + 3d = 0 or a = -3d …. (1) Similarly, a25 = a + 24d = -3d + 24d = 21d … (2) a11 = a + 10d = -3d + 10d = 7d …. (3) From (2) and (3), we have a25 = 3 x a11 Hence proved. ← Prev Question Next Question → Web30 mrt. 2024 · Here, a = 27, d = −3 We need to find which term is 0 ∴ an = 0 a + (n − 1)d = 0 27 + (n − 1) (−3) = 0 27 − 3n + 3 = 0 30 − 3n = 0 3n = 30 n = 30/3 n = 10 ∴ 10th term of AP is 0 Next: Question 5 (Choice - 2) → Ask a doubt Class 10 Solutions of Sample Papers for Class 10 Boards CBSE Class 10 Sample Paper for 2024 Boards - Maths Standard
