WebDec 28, 2024 · All you have to do is to add the first and last term of the sequence and multiply that sum by the number of pairs (i.e., by n/2). Mathematically, this is written as: S = n/2 × (a₁ + a) Substituting the arithmetic sequence equation for nᵗʰ term: S = n/2 × [a₁ + a₁ + (n-1)d] After simplification: S = n/2 × [2a₁ + (n-1)d] Web14．数列{an}满足nan+1-(n+1)an=0.已知a1=2．(I)求数列{an}的通项公式,(Ⅱ)若bn=$\frac{1}{2}{a n}$.Sn为数列$\left\{{\frac{1}{{2{b n}{b {n+1}}}}}\right ...

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, WebSold: 2 beds, 1 bath condo located at 230 5th Ave N Unit A1, Saint Cloud, MN 56303 sold for $117,500 on Apr 14, 2024.
