Question : Directions: Which letter cluster will replace the question mark (?) to complete the given series?
BRCQ, EPFO, ?, KLLK, NJOI
Option 1: HINO
Option 2: GNMI
Option 3: HNIM
Option 4: GINO
Correct Answer: HNIM
Solution :
Given:
BRCQ, EPFO, ?, KLLK, NJOI
Add 3 to the first and third letters and subtract 2 from the second and fourth letters of the previous term to obtain the next term in the series –
BRCQ→B + 3 = E; R – 2 = P; C + 3 = F; Q – 2 = O→EPFO
EPFO→E + 3 = H; P – 2 = N; F + 3 = I; O – 2 = M→HNIM
HNIM→H + 3 = K; N – 2 = L; I + 3 = L; M – 2 = K→KLLK
KLLK→K + 3 = N; L – 2 = J; L + 3 = O; K – 2 = I→NJOI
So, HNIM is the missing term in the series. Hence, the third option is correct.
