Question : Directions: In the following question, a series is given with one term missing. Choose the correct alternative from the given ones that will complete the series.
HIIJ, IJJK, JKKL, KLLM, LMMN, ?
Option 1: LNNO
Option 2: MNNP
Option 3: NOOP
Option 4: MNNO
Correct Answer: MNNO
Solution :
Given:
HIIJ, IJJK, JKKL, KLLM, LMMN, ?
Add 1 to the place value of each letter of the previous term to obtain the next term –
HIJJ→H + 1 = I; I + 1 = J; I + 1 = J; J + 1 = K
IJJK→I + 1 = J; J + 1 = K; J + 1 = K; K + 1 = L
JKKL→J + 1 = K; K + 1 = L; K + 1 = L; L + 1 = M
KLLM→K + 1 = L; L + 1 = M; L + 1 = M; M + 1 = N
LMMN→L + 1 = M; M + 1 = N; M + 1 = N; N + 1 = O
So, MNNO is the missing term. Hence, the fourth option is correct.
