B Correct answer
Explanation

The pattern is subtracting decreasing powers of 2 or specific increments. 7744 - 896 = 6848; 6848 - 648 = 6200; 6200 - 24 = 6176. The pattern is inconsistent; checking the differences: 896, 648, 24, 112, 56, 28, 14. The sequence of differences is halved starting from 112. Thus, 6200 should be 6176 + 112 = 6288.

AI explanation

The pattern involves subtracting a halving sequence of 896, 448, 224, 112, and 56. Subtracting 896 from 7744 gives 6848, and subtracting 448 from 6848 should give 6400, not 6200. Therefore, 6200 is the incorrect number.
