Solution For If an … WitrynaSince this holds for all n, we can plug in n=-1 and n=1 to get two equations: 1/-3=A/-1 +B/3. 1/5=A/1+B/5. Clean up the fractions to get -1=-3A+B and 1=5A+B. Subtract the second equation from the first to get -2=-8A, or A=1/4. So B=-1/4. So now, we're seeking the sum from n=1 to ∞ of (1/ (4n)-1/4 (n+4)). roshelle berliner production designer agent https://zigglezag.com

WitrynaSolution. Given: First term ( a) = a 1 = 1. n th term = a n = 20. Sum of n terms = S n = 399. Now, a n = a + n - 1 d ⇒ 20 = 1 + n - 1 d ⇒ n - 1 d = 20 - 1 ⇒ n - 1 d = 19... 1 S n = n 2 2 a + n - 1 d ⇒ 399 = n 2 2 1 + 19 From 1 ⇒ 399 = n 2 21 ⇒ 798 = 21 n ⇒ n = 798 21 ⇒ n = 38. Hence, the value of n is 38. Suggest Corrections. WitrynaIn an AP if a= 15 d = -3 and an = 0 then the value of n is 5 6 19 4 We have a= 15 and d = -3 Given an = 0 ⇒ a + n-1 d = 0 ⇒ 15 + n-1 -3 = 0
