A series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series.
YXW
Each term is three consecutive alphabet letters, alternating ascending and descending: CDE (asc), IHG (desc), KLM (asc), QPO (desc), STU (asc). So the next term must be descending.
The first letters are C(3), I(9), K(11), Q(17), S(19) with gaps +6, +2, +6, +2. The next gap is +6, giving 19 + 6 = 25 = Y. Writing three letters descending from Y: YXW.
What comes next?
