Correct Answer: FU
Solution :
Given:
DW, FU, IR, NM, UF, ?
Add and subtract consecutive prime numbers from the place value of the letters of each term.
DW→D + 2 = F; W – 2 = U
FU→F + 3 = I; U – 3 = R
IR→I + 5 = N; R – 5 = M
NM→N + 7 = U; M – 7 = F
UF→U + 11 = F; F – 11 = U
So, FU is the missing term of the series. Hence, the third option is correct.
