Question
Given that \(k-2, k-1\) and \(3k-5\) are three consecutive terms of an A.P. Find the possible values of k.
Correct Answer
Option A is the correct answer.
Detailed Explanation
For an AP, 2(k-1) = (k-2) + (3k-5) ⇒ 2k-2 = 4k-7 ⇒ -2k = -5 ⇒ k = 5/2.
Hint
For three consecutive terms of an AP, the middle term is the average: 2b = a + c.
