The world’s only live instant tutoring platform WebSolution: Let a and d be the first term and common difference of the A.P respectively. It is known that the k th term of an A.P. is given by a k = a + (k - 1) d Therefore, a m + n = a + (m + n - 1) d a m - n = a + (m - n - 1) d a m = a + (m - 1) d Hence, a m + n + a m - n = a + (m + n - 1) d + a + (m - n - 1) d = 2a + (m + n - 1 + m - n - 1) d

WebSolution Verified by Toppr Step -1: Finding the sum of first (m+n) terms. Let a be the first term and d be the common difference of the given A.P. ∵Formula for the sum of first n terms, S n=2n(2a+(n−1)d) According to the given question, S m=n ⇒ 2m(2a+(m−1)d)=n ⇒2am+m(m−1)d=2n…(i) and S n=m ⇒ 2n(2a+(m−1)d)=m ⇒2an+n(n−1)d=2m…(ii)
WebSolution: The sum of n terms S n = 441 Similarly, S n-1 = 356 a = 13 d= n For an AP, S n = (n/2) [2a+ (n-1)d] Putting n = n-1 in above equation, l is the last term. It is also denoted by a n. The result obtained is: S n -S n-1 = a n So, 441-356 = a n a n = 85 = 13+ (n-1)d Since d=n, n (n-1) = 72 ⇒n 2 – n – 72= 0 Solving by factorization method, how to remove google drive accountWebM* forthei than the amount received by them for such « nertismg KSKKNBS«BBBBWK8» * The Register’s Daily * * Bible Question Club * V By Rar.
