K + 3, k + 2, 3k – 7, 2k – 3
गणना
⇒ K + 3/k + 2 = 3k – 7/2k – 3
⇒ (K + 3)(2k – 3) = (k + 2)(3k - 7)
⇒ 2k2 - 3k + 6k -9 = 3k2 - 7k + 6k - 14
⇒ k2 - 4k - 5 = 0
⇒ (K + 1)(k – 5)
⇒ (K + 1) = 0 or (k – 5) = 0
⇒ k = -1 किंवा K = 5
किमान मूल्य विचारले असल्याने आपण k = -1 विचारात घेऊ
चौथे समानुपाती = 2k - 3 = -2 - 3 = -5
उत्तर -5 आहे.
