WebAnswer (1 of 8): we have to use the formula (a+(n-1)d) for ARITHMETIC PROGRESSION a is a first term in the AP n is a the term number or term location d is a common difference between successive terms in AP for the fifth term in AP TAKE a=2,d=3,n=5 a5=a+(n-1)d a5=2+(5–1)3 a5=2+(4)3 a5=14 ... 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 ...
WebIn an AP: (i) given a = 5, d = 3, a n = 50, find n a n d S n. (ii) given a = 7, a 13 = 35, find d a n d S 13. (iii) given a 12 = 37, d = 3, find a a n d S 12. (iv) given a 13 = 15, S 10 = 125, find d a n d a 10. 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
WebOn subtracting (1) from (2), we get S8 − S4 = 8 a + 28 d − (4 a + 6 d) = 4 a + 22 d Multiplying both sides by 3, we get 3 ( S8 − S4) = 3 (4 a + 22 d) = 12 a + 66 d = S12 [From (3)] Thus, S12 = 3 ( S8 − S4 ). Concept: Sum of First n Terms of an A.P. Is … WebIf Sn denotes the sum of first n terms of an AP, then prove that S12 =3(S8−S4) Solution ∵ Sum of n terms of an AP, Sn = n 2[2a+(n−1)d] ⋯(i) ∴ S8 = 8 2[2a+(8−1)d] = 4(2a+7d) =8a+28d And S4 = 4 2[2a+(4−1)d]= 2(2a+3d) = 4a+6d N ow, S8−S4 =8a+28d−4a−6d= 4a+22d ⋯(ii) And S12 = 12 2[2a+(12−1)d] =6(2a+11d)
WebHot spot (as shown in Fig. 8) is then formed due to the intensified C-H 2 reaction at the initial 2–5 min. Compared to the hydrogen inlet temperature (1,123 K), the temperature rise for 1 MPa is only 40 K, suggesting the CCHG reaction occurs slowly. With increasing pressure, the maximum temperature rises for 2 MPa, 3 MPa, and 4 MPa are 110 K ...
