Show answer & explanation
Correct answer: B
Pattern: each term is obtained by dividing the previous term by decreasing integers 6, 5, 4, 3, 2, 1.
2880 ÷ 6 = 480
480 ÷ 5 = 96 (expected), but the series shows 92 here
96 ÷ 4 = 24
24 ÷ 3 = 8
8 ÷ 2 = 4
4 ÷ 1 = 4
Conclusion: the wrong number in the given series is 92 because the correct term after 480 should be 96. The correct sequence is 2880, 480, 96, 24, 8, 4.
