Identify the wrong number in the series 2880, 480, 92, 24, 8, 4, 4

Concept

In a 'find the wrong number' series, each term is produced from the one before it by a single consistent operation. Here that operation is division by a steadily decreasing whole number (÷6, ÷5, ÷4, ÷3, ÷2, ÷1). The wrong number is the one term that breaks this chain.

Applying it here

1. 2880 ÷ 6 = 480 — matches the given term.

2. 480 ÷ 5 = 96 — but the series shows 92 here, so this term does not match.

3. 96 ÷ 4 = 24 — matches the given term.

4. 24 ÷ 3 = 8 — matches the given term.

5. 8 ÷ 2 = 4 — matches the given term.

6. 4 ÷ 1 = 4 — matches the given term.

Cross-check

Every other term in the series satisfies the ÷6, ÷5, ÷4, ÷3, ÷2, ÷1 pattern exactly; only 92 fails to match its expected value, confirming 92 is the wrong number in the series.
