Which of the following terms will replace the question mark (?) in the given…

To solve this letter series, we need to determine the shifting pattern between the letters of consecutive terms: MFT, NIS, PLQ, SON, WRJ.

Step-by-Step Pattern Analysis
Let's look at the shift for each position in the three-letter terms:

First Letter Shift:

M to N (+1)

N to P (+2)

P to S (+3)

S to W (+4)

Next shift should be +5: W + 5 = B (W, X, Y, Z, A, B)

Second Letter Shift:

F to I (+3)

I to L (+3)

L to O (+3)

O to R (+3)

Next shift should be +3: R + 3 = U

Third Letter Shift:

T to S (-1)

S to Q (-2)

Q to N (-3)

N to J (-4)

Next shift should be -5: J - 5 = E

Solution
The next term in the series is BUE. Each position follows its own specific arithmetic progression: the first letter increases by an increment of 1 (+1, +2, +3, +4, +5), the second letter maintains a constant increase of +3, and the third letter decreases by an increment of 1 (-1, -2, -3, -4, -5).
