Question : Directions: Select the letter-cluster that can replace the question mark (?) in the following series.
TXB, QWE, NVH, KUK, ?
Option 1: ITM
Option 2: HSN
Option 3: JTM
Option 4: HTN
Correct Answer: HTN
Solution :
Given:
TXB, QWE, NVH, KUK, ?
Subtract 3, 1 in the first and second letter respectively, and add 3 in the positional value of the third letter to obtain the required code –
TXB → T – 3 = Q, X – 1 = W, B + 3 = E → QWE
QWE → Q – 3 = N, W – 1 = V, E + 3 = H → NVH
NVH → N – 3 = K, V – 1 = U, H + 3 = K → KUK
KUK → K – 3 = H, U – 1 = T, K + 3 = N → HTN
Therefore, the required missing term in the series is HTN. Hence, the fourth option is correct.
