Look at each letter position independently across the terms: 1st letters increase by +2, 2nd letters increase by +2, and 3rd letters increase by +2.
Step 1: Analyze 1st Letters
G (+2) тЖТ I (+2) тЖТ K (+2) тЖТ M (+2) тЖТ O. The 1st letter of the missing term is O (position 15).
Step 2: Analyze 2nd Letters
J (+2) тЖТ L (+2) тЖТ N (+2) тЖТ P (+2) тЖТ R. The 2nd letter of the missing term is R (position 18).
Step 3: Analyze 3rd Letters
F (+2) тЖТ H (+2) тЖТ J (+2) тЖТ L (+2) тЖТ N. The 3rd letter of the missing term is N (position 14).
Step 4: Form the Final Term
Combining the letters O, R, and N gives the final term ORN, which matches Option D.
A: ONR has wrong middle letter, B: RNO has completely reversed order, C: RON has incorrect letter sequence
D is correct because each letter position advances by +2 in the English alphabet, resulting in ORN.
Always break down multi-letter groups into independent positional series (1st, 2nd, 3rd) to solve quickly without confusion.
