Choose the set of letters that sequentially completes the following letter series.
uw_wuv_vuwu_uvu_
Show answer & explanation
Correct answer: C
Explanation
Count the total number of characters (letters and blanks): 16.
Divide the series into 4 equal groups of 4 letters each:
uw _ w / uv _ v / uwu _ / uvu _
By filling in the blanks with the letters u, u, w, v from option (C), we get:
uwuw / uvuv / uwuw / uvuv
A clear alternating pattern of uwuw and uvuv is formed.
Therefore, the missing letters are u u w v.
