If the pth term of an AP is k, then what is the sum of the pth, (p+q)th and (p-q)th terms of this AP?

  1. A.2k
  2. B.3k✓ Correct
  3. C.4k
  4. D.5k

Explanation

The (p+q)th and (p-q)th terms are equidistant from the pth term, so their sum equals 2 × (pth term) = 2k. Adding the pth term itself: k + 2k = 3k.
