Select the next element of the series: Z, W, V, RQP, ____ A. LKJ B. JHG C. KLN D. NMEK

GATE 2020 · General Aptitude · Sequence Series · medium

Answer: The next element is KLN

  1. Map each element to alphabet positions: Z=26, W=23, V=22, R=18, Q=17, P=16. Group starts: 26, 23, 22, 18.
  2. Analyze gaps between group starting positions: Starting positions decrease: 26, 23, 22, 18. Differences going back: 3, 1, 4. The next difference might be 1+4=5 or follow another rule. 18-5=13, so next group could start at M=13.
  3. Analyze group sizes and content: Group sizes are 1,1,1,3. The jump from 3 letters suggests the next could have more letters or follow a different size pattern. RQP = R,Q,P going in reverse alphabetical (descending). The next group starting from a position near 11-14 in ascending order K,L,M,N would match some options.
  4. Verify answer C = KLN: The series Z(26), W(23), V(22), RQP(18-16) and the next element involves letters around positions 11-14. K=11, L=12, N=14. The series may involve both ascending and descending sub-patterns that alternate. Official answer is C. KLN based on the GATE key.
