Answer 1

Answer:

B. IN67

1. First Letter:

• E → F (+1)

• F → G (+1)

• G → H (+1)

• H → I (+1)

2. Second Letter:

• J → K (+1)

• K → L (+1)

• L → M (+1)

• M → N (+1)

3. Numbers:

• 23 → 34 (+11)

• 34 → 45 (+11)

• 45 → 56 (+11)

• 56 → 67 (+11)

Combining these components (I, N, and 67), the cluster that replaces the question mark is IN67.
