Logical Reasoning (MTS) Inserting the missing Character

Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.

GA, MU, SO, ?, EC

Let’s break this down:

- First, look at the first letters: G, M, S, ?, E

- Their positions in the alphabet: G(7), M(13), S(19), ? , E(5)

- Notice the jump: G to M = +6, M to S = +6, S to ? should be +6, so S(19) + 6 = 25, which is Y.

- Next, the second letters: A, U, O, ?, C

- Alphabet positions: A(1), U(21), O(15), ?, C(3)

- How’s the step? A ? U: +20, U ? O: -6, O ? ? , then ? ? C

- Now, O(15) to C(3): That's -12.

- So the sequence backward is: +20, -6, -12. That’s reducing by 6 each time.

- So from U(21) to O(15), -6. Next gap: -6 more, so 15 - 12 = 3. From O(15) to ? would be -6, so 15 - 6 = 9, which is I.

Now, plug these together: the answer is YI

Here’s how the options line up:

- ZI – not matching first gap logic.

- ZJ – same, off on the first letter.

- YJ – right first letter, wrong second.

- YI – matches both letter patterns.
