Find the next term in the series
XRF, UTI, RVM, __________.

The logic for the nth term first letter of the series = previous series first letter - 3 

 The logic for the nth term second letter of the series = previous series second letter + 2

The logic for the nth term third letter of the series = previous series third letter + n + 1

So, the 4th term is given as,

1st letter = R - 3 = O

2nd letter = V + 2 = X

3rd letter = M + 4 + 1 = R

So, the next term of the series is OXR.

Therefore, the correct answer is option B.
