WebMar 29, 2024 · Given : t7= 4 , d = -4 . Solution : tn = a + (n - 1) d .....( formula) t7 = a + (7 - 1) (-4) 4 = a + (6)( - 4) 4 = a - 24. 4 + 24 = a. 28 = a. therefore, the first term (a) is 28. WebLet a be the first term and d be the common difference of AP. We know that. an = a +(n − 1)d. ∴ a 21 = a +(21 − 1)d = a + 20d. and a 7 =a + (7 − 1)d = a + 6d. Given: a 21 − a 7 = 84. ∴ (a + 20d) − (a + 6d) = 84. ⇒ a + 20d − a − 6d = 84. ⇒14d = 84. ⇒ d = 6. Thus, the common difference of the AP is 6 WebIf an be the nth term of an A.P. and if a7 = 15, then the value of the common difference that would make a2a7a12 an greatest is (A) 9 (B) (5/4) (C) 0 .
