Q.No.2: the 20th term of Arithmetic Progressionfrom ending is (a) (B) (c) (D)A.P.IS 22,25 28,31,-----------322 |
|
Answer» Answer: 265 Step-by-step EXPLANATION: Here, Common difference = d = 28 - 25 = 25 - 22 = 3 From ending AP looks like: 322...31, 28, 25, 22, and thus common difference becomes negative( now that is - 3 ). In APs nth term is GIVEN by a + ( n - 1 )d, where a is the first term and d is the common difference. From ending first term is 322 and common difference is - 3. Therefore, 20th term from last: ⇒ 322 + ( 20 - 1 )( - 3 ) ⇒ 322 + 19( - 3 ) ⇒ 322 - 57 ⇒ 265 |
