Select the term that will come next in the following series.
ELFA, GLHA, ILJA, _____, MLNA
Answer & explanation
Correct answer: option 3

Explanation:
ELFA, GLHA, ILJA, _____, MLNA
The logic followed here is :
E → (+2) → G → (+2) → I → (+2) → K → (+2) → M
L → (0) → L → (0) → L → (0) → L → (0) → L
F → (+2) → H → (+2) → J → (+2) → L → (+2) → N
A → (0) → A → (0) → A → (0) → A → (0) → A
So, the letter-cluster that replaces the (?) to complete the series is "MLNA"
