Question

Choose the answer choice that can replace the '?' in the series.

R, M, ?, F, D, ?

• A. C, B
• B. J, H
• C. H, C
• D. I, C

Answer 1

The correct option is D I, C

Each letter moves four, three, two, one step backwards in alphabetic order.
R$\to$M (4 letters gap)
M$\to$I (3 letters gap)
I$\to$F (2 letters gap)
F$\to$D (1 letters gap)
D$\to$C (No gap)

Hence, $I,C$ are missing alphabets.
