Which of the following terms will replace the question mark (?) in the given series?
RJO, SKP, TLQ, ?

The correct answer is UMR.

Let us analyze the pattern in the given series of letter groups: RJO, SKP, TLQ, ?

We can determine the next term by examining the transition of each letter position (first, second, and third) from one term to the next:

First Letter:
The first letters of the terms are: R, S, T, ...
These letters follow the consecutive alphabetical order:
R (+1) → S
S (+1) → T
T (+1) → U

Second Letter:
The second letters of the terms are: J, K, L, ...
These letters also follow the consecutive alphabetical order:
J (+1) → K
K (+1) → L
L (+1) → M

Third Letter:
The third letters of the terms are: O, P, Q, ...
These letters also follow the consecutive alphabetical order:
O (+1) → P
P (+1) → Q
Q (+1) → R

Combining the next letter from each position (U, M, and R), we get the term UMR.
