Question

Choose the correct alternative from the given options that will complete the series.
BC2, GH3, LM5, QR7, ?

• A. VW10
• B. VW11
• C. XW11
• D. RS10

Hint:

Alpha-numeric series problems usually have two independent patterns: one for the letters and one for the numbers. Solve them separately and then combine the results.

Answer 1

The Correct Option is B

Step 1: Letter pattern analysis:

• BC \(\rightarrow\) skip 3 letters \(\rightarrow\) GH
• GH \(\rightarrow\) skip 3 letters \(\rightarrow\) LM
• LM \(\rightarrow\) skip 3 letters \(\rightarrow\) QR
• QR \(\rightarrow\) skip 3 letters \(\rightarrow\) VW

Step 2: Number pattern analysis: The sequence 2, 3, 5, 7 consists of prime numbers.
Step 3: Combine patterns: The next letter pair is VW. The next prime number after 7 is 11. The next term is VW11.
