In a certain code language, 'DZLV' is coded as 'HDJT' and 'CQYH' is coded as 'GUWF". What is the code for 'MTBE in the given code language?

Given: DZLV → HDJT, CQYH → GUWF, MTBE →? 

Logic: The first two letters increase by +4, while the last two letters decrease by -2.

D +4 → H, Z + 4 → D, L -2 → J, V -2 → T

CQYH → GUWF

C + 4 → G, Q + 4 → U, Y - 2 → W, H - 2 → F

The pattern followed is: (+4, +4, -2, -2) for consecutive letters.

Applying the Same Pattern to MTBE:

M +4 → Q, T +4 → X, B -2 → Z, E -2 → C

Thus, MTBE → QXZC
