Question

In the given number series, one of the numbers is not belonging to that series, the number is: 3F, 6G, 11L, 18L, ?

• A. 21 Q
• B. 25 N
• C. 27 Q
• D. 27 P

Hint:

When solving such series, identify both the numerical and alphabetical patterns.

Answer 1

The Correct Option is B

To determine which number does not belong in the series, we need to analyze the given pairs:

• 3F
• 6G
• 11L
• 18L

Next, let's find the pattern in both numbers and letters:

• Numbers:Observe the difference between the numbers.
  • 6 - 3 = 3
  • 11 - 6 = 5
  • 18 - 11 = 7
  • 18 + 9 = 27
• Letters:Consider the alphabetical order:
  • F is the 6th letter
  • G is the 7th letter
  • L is the 12th letter
  • L is repeated
    • From F (6th) to G (7th) is +1
    • From G (7th) to L (12th) is +5
    • The letter corresponding with 27 should be 12 (L) with a shift of 1, resulting in 13 (M)

Therefore, the number that does not logically fit based on the provided options is 25 with letter N as 14th letter, breaking the series pattern.

Option	Reason
21 Q	Does not follow the numerical sequence.
25 N	Does not belong due to disrupting the expected number pattern.
27 Q	Complete number aligns with derived series, but letter has a mismatch if considered logically.
27 P	Best approximate next logical choice in series with common interpretation of given letter patterns but is misaligned originally.

This analysis ascertains that the choice with the letter 'N,' or 25 N, stands out as not belonging to the sequence logically compared to the others.
