Question 36 (ii) Find the 34th term of progression written by Roshan.Second AP by Roshan is 187, 184, 181, …. Here, First term = a = 187 Common difference = d = –3 We need to find 34th term Using formula an = a + (n – 1)d Putting a = 187, d = –3, n = 34 a34 = 187 + (34 – 1) × (–3) a34 = 187 + 33 × (–3) a34 = 187 – 33 × 3 a34 = 187 – 99 a34 = 88 Thus, required term is 88
