Explanation:

To find the wrong number in the given series, we need to identify the pattern followed by the numbers. Let's analyze the given series step by step:

1. The first number in the series is 7.5.
2. The difference between the first and second numbers is 40 (47.5 - 7.5).
3. The difference between the second and third numbers is 40 (87.5 - 47.5).
4. The difference between the third and fourth numbers is 40 (157.5 - 87.5).
5. The difference between the fourth and fifth numbers is 40 (247.5 - 157.5).
6. The difference between the fifth and sixth numbers is 40 (357.5 - 247.5).
7. The difference between the sixth and seventh numbers is 40 (487.5 - 357.5).

Pattern:
From the analysis, we can observe that the series is increasing by 40 in each step. However, there is a mistake in the series.

Finding the Wrong Number:
To find the wrong number, we need to find the number in the series that does not follow the pattern of increasing by 40.

In the given series, all the numbers except the last one (487.5) are correct. The last number in the series should be 527.5 (357.5 + 40), but instead, it is given as 487.5.

Therefore, the wrong number in the series is 487.5.

Conclusion:
The wrong number in the given series is 487.5.
