Answer» According to the QUESTION, 24th term = 2( 10th term ) a + 23d = 2 ( a + 9d ) a + 23d = 2a + 18d 23d - 18d = 2a - a 5d = a ----1equation Hence, To Prove : 36th term = 2( 16 th term ) RHS = 2 ( a + 15 d ) = 2a + 30d = 2( 5d ) + 30d = 10d + 30d = 40d LHS = 36th term = a + 35D = 5d + 35d = 40d 40d = 40d RHS = LHS |
