Consider the letter series S       T        V        ___         C In this series between S and T no letter is skipped Between T and V one letter U is skipped Hence after V we should skip two letters W and X to find the missing letter Therefore the answer is Y
After Y if we skip three letters (i.e. Z, A and B) we get the letter C which is the next letter pf the series
The other series is C        B        A         Z These are all consecutive letters in the reverse order The pattern can be indicated as follows.
