Observe the first, second, and third letters of each cluster independently; each position follows a +1 progression through the alphabet.
Analyze the 1st letter of each cluster
F(6) → G(7) → H(8) → I(9) → J(10). The next 1st letter is J.
Analyze the 2nd letter of each cluster
I(9) → J(10) → K(11) → L(12) → M(13). The next 2nd letter is M.
Analyze the 3rd letter of each cluster
K(11) → L(12) → M(13) → N(14) → O(15). The next 3rd letter is O.
Combine letters to form the final cluster
Combining the results J, M, O, the final cluster is JMO.
A: JOM is incorrect because the second letter must be M and the third must be O. B: OMJ is incorrect because it changes the order of the established progression. C: OJM is incorrect because the progression dictates J as the first letter, not O.
D is correct because the series follows a consistent +1 increment for every letter position, resulting in J(10), M(13), O(15).
Always break down three-letter clusters into three separate series; often, each individual series is a simple +1 or +2 progression.
