Which term comes next in the sequence : AC, FH, KM, PR, ?
Correct
Clearly, the first and second letters of each term are moved five steps forward to obtain the corresponding letters of the next term.
Thus, the first letter of the missing term must be five steps ahead of P i.e. U, while the second letter must be five steps ahead of R i.e. W.
So, the missing term is UW.
