Question

In the following series, find the correct options at the place of the question mark. Q1F, S2E, U6D, W21C, ?

• A. Z88B
• B. Y88B
• C. Y66B
• D. Z44A
• E. Y44B

Hint:

In alphanumeric series, treat letters and numbers separately to find patterns.

Answer 1

The Correct Option is B

Step 1: Break into three parts: letter, number, letter. First part: Q, S, U, W, ? → Q(17), S(19), U(21), W(23), next is Y(25). So next letter is Y.
Step 2: Last letter: F, E, D, C, ? → F(6), E(5), D(4), C(3), next is B(2). So last letter is B.
Step 3: Middle numbers: 1, 2, 6, 21, ? Pattern: 1×2+0=2? Let's check: 1×1+1=2? Actually 1×1+1=2, 2×2+2=6, 6×3+3=21, so pattern: multiply by increasing integer and add same integer: 1×1+1=2, 2×2+2=6, 6×3+3=21, next: 21×4+4=84+4=88.
Step 4: So the next term is Y88B.
Step 5: Final Answer: Y88B.
