Identifying the Wrong Number:
- To identify the wrong number in the series, we need to look for any pattern or rule that the numbers follow.
Pattern in the Series:
- When we look at the given numbers, we can see that they are all perfect squares of consecutive integers.
- 529 = 23^2, 841 = 29^2, 961 = 31^2, 1296 = 36^2, 1681 = 41^2, 1849 = 43^2, 2209 = 47^2.
Finding the Wrong Number:
- The wrong number in the series is the one that does not follow the pattern of being a perfect square of a consecutive integer.
- Among the given options, 1296 is the only number that does not fit the pattern. It is the square of 36, but the next perfect square after 36 (41^2) is 1681, not 1296.
Therefore, the wrong number in the series is 1296 (option A).
