The answer is C. 10.
The series is a list of squares of consecutive prime numbers. The first three prime numbers are 2, 3, and 5. The squares of these numbers are 4, 9, and 25. The next three prime numbers are 7, 11, and 13. The squares of these numbers are 49, 121, and 169. The next number in the series should be 169, but it is 10. Therefore, 10 is the wrong term.
Here is a table showing the squares of the first 13 prime numbers:
Prime number | Square ------- | -------- 2 | 4 3 | 9 5 | 25 7 | 49 11 | 121 13 | 169 17 | 289 19 | 361 23 | 529 29 | 841 31 | 961 37 | 1369 41 | 1681
As you can see, the squares of the prime numbers are all odd numbers. Therefore, 10, which is an even number, is the wrong term in the series.
