TīmeklisShow that the ratio of the sum of first n terms of a G.P to the sum of terms from (n + 1) th to (2n) th term is 1/r n Solution: Let a be the first term and r be the common ratio of the G.P. Sum of first n terms, S = [a (1 - r n )/ (1 - r)] Since, there are n terms from (n + 1) th to (2n) th term. Tīmeklis2024. gada 17. janv. · The series is convergent and: ∞ ∑ n=1 2n n! = e2 −1 Explanation: The ratio test states that a sufficient condition for a series: ∞ ∑ n=0an to converge absolutely is that: L = lim n→∞ ∣∣ ∣ an+1 an ∣∣ ∣ < 1 We then evaluate the ratio for the series: ∞ ∑ n=1 2n n! ∣∣ ∣ an+1 an ∣∣ ∣ = 2n+1 (n+1)! 2n n! = 2n+1 2n n! (n +1)! = 2 n …
TīmeklisThe sum of n terms of two arithmetic progressions are in the ratio (3n + 8) : (7n + 15). Find the ratio of their 12th terms. Solution Let a1, a2 and d1, d2 be the first terms and common differences of the first and second AP respectively. Then, by the given condition, we have sum to n terms of first AP sum to n terms of second AP = 3n+8 … TīmeklisThe ratio of the sums of m and n terms of an A.P is m 2:n 2. Show that the ratio of m th and n th term is (2m−1):(2n−1). Medium Solution Verified by Toppr Let S m and S n be the sum of the first m and first n terms of the AP respectively. Let, a be the first term and d be a common difference S nS m= n 2m 2 ⇒ 2n[2a+(n−1)d] 2m[2a+(m−1)d]= n 2m 2
Tīmeklis2024. gada 5. sept. · If the ratio of sums to n terms of two A.P's is (5n+7):(3n+2), then the ratio of their 17 th terms is?

The Ratio Test states that if this limit is greater than 1, the series diverges. Less than 1, it converges. If it is exactly 1, the test is inconclusive. Because ∞ is obviously greater than 1, the series diverges. Answer link. ncs220 ネグロス
