The correct answer is

PLR

Compare each cluster with the next, letter by letter, moving through the alphabet cyclically (after Z comes A).

First letters: R(18) → K(11) → D(4) → W(23) each drop by 7 (with wrap-around from D to W: 4 − 7 = −3, plus 26 = 23). So the next first letter is W(23) − 7 = P(16).

Second letters: N(14) → G(7) → Z(26) → S(19) each drop by 7 (with wrap-around). The next second letter is S(19) − 7 = L(12).

Third letters: T(20) → M(13) → F(6) → Y(25) each drop by 7 (F to Y wraps: 6 − 7 = −1, plus 26 = 25). The next third letter is Y(25) − 7 = R(18).

Combining P, L and R gives PLR.

Hence, the missing term is PLR.
