Which set of letters when sequentially placed at the gaps in the given letter series shall complete it?
j _ l _ j k _ m _ k l _
- Ajkljm
- Bkmjjj
- Ckmljm
- Dmkjlm
Solution & Step-by-step Explanation
The given series has 12 positions. Let's divide it into 3 groups of 4 letters each:
\text{j _ l _ } | \text{ j k _ m } | \text{ _ k l _}
By comparing the groups to find a repeating pattern:
The second group is j k _ m. This suggests the pattern follows the alphabetical sequence j k l m.
Applying j k l m as the repeating unit to all three blocks:
First block: j [k] l [m]
Second block: j k [l] m
Third block: [j] k l [m]
Putting the inserted letters together in order: k, m, l, j, m.
Thus, the correct set of letters is kmljm.
\text{j _ l _ } | \text{ j k _ m } | \text{ _ k l _}
By comparing the groups to find a repeating pattern:
The second group is j k _ m. This suggests the pattern follows the alphabetical sequence j k l m.
Applying j k l m as the repeating unit to all three blocks:
First block: j [k] l [m]
Second block: j k [l] m
Third block: [j] k l [m]
Putting the inserted letters together in order: k, m, l, j, m.
Thus, the correct set of letters is kmljm.
