The term that should come in place of the question mark (?) is GNA.
1. First Letter Position: K → J → I → H → ?
The letters are moving backward by 1 position in alphabetical order.
K (-1) = J
J (-1) = I
I (-1) = H
H (-1) = G
2. Second Letter Position: V → T → R → P → ?
The letters are moving backward by skipping 1 letter (subtracting 2 positions).
V (-2) = T
T (-2) = R
R (-2) = P
P (-2) = N
3. Third Letter Position: M → J → G → D → ?
The letters are moving backward by skipping 2 letters (subtracting 3 positions).
M (-3) = J
J (-3) = G
G (-3) = D
D (-3) = A
Combining all three results gives GNA.
