Explanation:

- The sequence starts with 6 and progresses as follows: 6, 4, 5, 11, 39, 179, 1127.

- Calculate the difference between successive terms to find the pattern or any anomaly.

- Differences are: 6 to 4 is -2, 4 to 5 is +1, 5 to 11 is +6, 11 to 39 is +28, 39 to 179 is +140, 179 to 1127 is +948.

- These differences have no obvious pattern.

- Reanalyze by calculating the ratios between consecutive terms: 4/6, 5/4, 11/5, 39/11, 179/39, 1127/179.

- Ratios are approximately: 0.67, 1.25, 2.2, 3.54, 4.59, 6.29.

- No consistent pattern in the ratios is observed, suggesting an error.

- Option 3 (179): This number breaks any multiplicative or additive sequence.

- Option 3, 179 is indeed the anomaly, as the pattern can't naturally progress to this number.

- Answer: Option 3: 179 is the correct answer.
