Webd. 104.5. Solution: An arithmetic progression (AP) is a sequence where the two consecutive terms have the same common difference. It is obtained by adding the same fixed number to its previous term. The nth term of an AP is. aₙ = a + (n - 1 )d. a = first term. aₙ = nth term. d = common difference. Considering the question, we get the value as, WebSince few users ever read sources, credits * must appear in the documentation. * * 3.

WebBalls are arranged in rows to form an equilateral triangle. The first row consists of one ball, the second row of two balls and so on. If 669 more balls are added then all the balls can be arranged in the shape of a square and each of the sides then contains 8 balls less than each side of the triangle did. WebIn an AP, if the common difference (d) = -4 and the seventh term (a 7) is 4, then find the the first term. Hard Solution Verified by Toppr we know, a n=a+(n−1)d so, a 7=a+(7−1)d or, … WebIn an AP, if d = –4, n = 7, an=4, then a is (A) 6 (B) 7 (C) 20 (D) 28. Browse by Stream Login. QnA. Home. QnA.
