Correct Answer: HQR
Solution : Given:
TMJ, QNL, NON, KPP, ?
Each letter of the letter cluster is following a different pattern as follows –
First letter of each letter cluster is 3 less than the first letter of previous letter cluster.
T – 3 = Q → Q – 3 = N → N – 3 = K
Therefore, first letter of next letter cluster is K – 3 = H .
Second letter of each letter cluster is consecutive alphabets (M, N, O, P). Therefore, second letter of next cluster is Q .
Third letter of each letter cluster is obtained on adding 2 to each third letter of previous letter cluster (J, L, N, P)
J + 2 = L → L + 2 = N → N + 2 = P → P + 2 = R
Therefore, third letter of next cluster is R ,
Thus, HQR is the missing term and the series is as follows –
TMJ, QNL, NON, KPP, HQR
Hence, the second option is correct.
