WebMar 28, 2024 · Ex 5.3, 3 In an AP (iii) Given a12 = 37, d = 3, find a and S12. Given a12 = 37, d = 3 Finding a We know that an = a + (n – 1) d Putting d = 3, n = 12 and a12 = 37 37 = a + (12 – 1) × 3 37 = a + 11 × 3 37 = a + 33 37 − 33 = a 4 = a a = 4 Now, we can find (S12) by using formula Sn = 𝒏/𝟐 (𝒂+𝒍) Putting n = 12 , a = 4, 𝑙 = a12 ... WebTo find out the common difference in an AP you can perform the following simple step. Explanation: Subtract the first term of the AP from the second term of the AP. d = a2 - a1 where d = common difference a2 = any term other than first term a1 = previous term For example; In the AP 3 , 9 , 15 , 21 , 27 , 33 Taking a1 = 3 Taking a2 = 9 songtext more than a feeling
