Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
NFP, MHM, LJJ, KLG, ?
- AJND
- BKMF
- CJME
- DKND
Solution & Step-by-step Explanation
Let's analyze the pattern letter by letter across the series:
First Letter: N, M, L, K, ?
N(14)−1=M(13)
M(13)−1=L(12)
L(12)−1=K(11)
K(11)−1=J(10)
Second Letter: F, H, J, L, ?
F(6)+2=H(8)
H(8)+2=J(10)
J(10)+2=L(12)
L(12)+2=N(14)
Third Letter: P, M, J, G, ?
P(16)−3=M(13)
M(13)−3=J(10)
J(10)−3=G(7)
G(7)−3=D(4)
Combining the results gives the cluster: JND.
