In the given number series, one of the numbers is not belonging to that series, the number is: 3F, 6G, 11L, 18L, ?
In the given number series, one of the numbers is not belonging to that series, the number is: 3F, 6G, 11L, 18L, ?
Show Hint
- 21 Q
- 25 N
- 27 Q
- 27 P
The Correct Option is B
Solution and Explanation
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.
