Analyze the position numbers of each letter in the English alphabet independently for the 1st, 2nd, and 3rd letters across the series terms.
Analyze the position numbers of each letter in the English alphabet independently for the 1st, 2nd, and 3rd letters across the series terms.
Analyze 1st Letters
The first letters are N (14), P (16), R (18), T (20). Each letter increases by +2 in alphabetical position. T (20) + 2 = V (22).
Analyze 2nd Letters
The second letters are J (10), L (12), N (14), P (16). Each letter increases by +2 in alphabetical position. P (16) + 2 = R (18).
Analyze 3rd Letters
The third letters are M (13), O (15), Q (17), S (19). Each letter increases by +2 in alphabetical position. S (19) + 2 = U (21).
Form Final Term
Combining the calculated letters (V, R, U) gives the next term in the series: VRU.
A: RUV is incorrect because the first letter must be V (+2 pattern from T). C: RVU is incorrect because the second and third letters are swapped. D: VUR is incorrect because the third letter must be U.
B is correct because each letter in the triplet advances by +2 positions in the English alphabet, leading from TPS to VRU.
Always check positional increments independently for multi-letter cluster series to avoid transposition errors.
