Select the wrong term in the given alpha-numeric series.

L11, O22, R44, U44, X55​​

Given: L11, O22, R44, U44, X55​​

Logic: Letters are increasing + 3 place and number is increasing multiple of 11.

L + 3 → O, O + 3 → R, R + 3 → U, U + 3 → X

11 $$\times$$ 1 = 11, 11 $$\times$$​ 2 = 22, 11 $$\times$$​ 3 = 33 $$\neq$$ 44, 11$$\times$$ 4 = 44, 11$$\times$$ 5= 55

So, the wrong term is R44.

Thus, correct option is (c).
