Question

In the following series, one number is incorrect. Identify the wrong number:

2, 4, 7, 13, 19, 30, 43

Accepted Answer

**Solution:**

1. Observe the series: 2, 4, 7, 13, 19, 30, 43

2. Let's analyze the differences between consecutive terms:
   - 4 - 2 = 2
   - 7 - 4 = 3
   - 13 - 7 = 6
   - 19 - 13 = 6
   - 30 - 19 = 11
   - 43 - 30 = 13

3. The differences do not follow a consistent pattern. Let's check if the series fits a pattern where each term is the sum of the previous two terms or some other pattern.

4. Alternatively, check if the series is close to a pattern of adding consecutive prime numbers:
   - 2 + 2 = 4
   - 4 + 3 = 7
   - 7 + 5 = 12 (but the series has 13 here, which is incorrect)

5. The correct term after 7 should be 12, not 13.

6. Continuing with this pattern:
   - 12 + 7 = 19
   - 19 + 11 = 30
   - 30 + 13 = 43

7. Hence, the wrong number in the series is **13**.

**Answer:** 13
