Which letter-cluster should replace # and % so that the pattern is consistent:
GDI
HIK
GHK
FGI
GHK
Look at the pattern J(10) L(12) O(15) and Q(17) T(20) V(22). Identify the interval difference between letter groups: +2, +3 for the first and +3, +2 for the second, then map the relationship backward.

Analyze the relationship between JLO and QTV
J(10), L(12), O(15). Pattern is +2, +3. For Q(17), T(20), V(22), the pattern is +3, +2.
, we need a group that transforms into JLO with the same logic that QTV transforms into the missing term.
Identify the logic for #
If the pattern is J-3=G, L-1=K, O-4=K (Wait, let's re-evaluate). Let's check GHK: G(7), H(8), K(11). From G(7) to J(10) is +3. From H(8) to L(12) is +4. From K(11) to O(15) is +4. Checking QTV: Q(17)+? = %... Actually, the relationship is positional: J(10) to Q(17) is +7. L(12) to T(20) is +8. O(15) to V(22) is +7. So G(7)+7=N, H(8)+8=P, K(11)+7=R.
Verification of GHK
Testing GHK against JLO: G(7)+3=J(10), H(8)+4=L(12), K(11)+4=O(15). This +3, +4, +4 sequence is consistent with a shift. Specifically, J-3=G, L-4=H, O-4=K. Thus, GHK is the cluster that precedes JLO.
A: GDI leads to index 7, 4, 9 which does not follow the +3, +4, +4 logic. B: HIK leads to index 8, 9, 11 which deviates from the required jump sequence. D: FGI leads to index 6, 7, 9 which results in an incorrect positional shift when compared to JLO.
C is correct because the letter-cluster GHK follows the positional rule where each letter corresponds to JLO by adding 3, 4, and 4 respectively.
In analogy questions, if the patterns are not immediately obvious with simple shifts, always write down the numerical values of the letters to find the constant addition or subtraction.
