Now the teacher asks his various students the following questions on progression.First AP by Aryan is –5, –2, 1, 4, …. Here, First term = a = –5 Common difference = d = (–2) – (–5) = –2 + 5 = 3 Second AP by Roshan is 187, 184, 181, …. Here, First term = a = 187 Common difference = d = 184 – 187 = –3 Question 36 (i) Find the sum of the common difference of two progressions.Sum of common difference = Common difference of 1st AP + Common Difference of 2nd AP = 3 + (–3) = 3 – 3 = 0
