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: Analyze the pattern of the letters. - BC \(\rightarrow\) skip D,E,F (3 letters) \(\rightarrow\) GH - GH \(\rightarrow\) skip I,J,K (3 letters) \(\rightarrow\) LM - LM \(\rightarrow\) skip N,O,P (3 letters) \(\rightarrow\) QR - QR \(\rightarrow\) skip S,T,U (3 letters) \(\rightarrow\) VW
Step 2: Analyze the pattern of the numbers. The numbers in the series are 2, 3, 5, 7. This is the sequence of prime numbers.
Step 3: Combine the patterns to find the next term. The next pair of letters is VW. The next prime number after 7 is 11. Therefore, the next term in the series is VW11.
