Concept:Convert letters to their positional values and check the gap pattern.Explanation:For DGJ: D=4, G=7, J=10; gaps are +3 and +3.For KNQ: K=11, N=14, Q=17; gaps are +3 and +3.For RUX: R=18, U=21, X=24; gaps are +3 and +3.For ILN: I=9, L=12, N=14; gaps are +3 and +2.Thus, ILN does not follow the equal-gap pattern.
