Find the wrong term in the following series:
LO, HK, DG, ZC, UX

Correct option is C

Given Series:
LO, HK, DG, ZC, UX

We need to determine the incorrect term in the sequence.

Step 1: Checking the Pattern
Each pair consists of two letters, so let's analyze them separately.

First Letters: L, H, D, Z, U
L (12), H (8), D (4), Z (26), U (21)
Observing the pattern:
L → H → D follows a pattern of decreasing by 4:
(L=12 → H=8 → D=4)
However, Z=26 does not fit the pattern, as the sequence should continue with Z=0 (not valid in the alphabet).
Second Letters: O, K, G, C, X
O (15), K (11), G (7), C (3), X (24)
Observing the pattern:
O → K → G → C follows a pattern of decreasing by 4:
(O=15 → K=11 → G=7 → C=3)
However, X=24 does not fit the pattern, as it should have been Y=(-1) (not valid in the alphabet).
Step 2: Identifying the Incorrect Term
The expected pattern should continue decreasing uniformly.
The last term "UX" (U=21, X=24) breaks the pattern, as X should have followed the decreasing trend instead of jumping up.
Final Answer:
Option c: UX is the incorrect term.
