A Correct answer
Explanation

The series is 196 (14^2), 169 (13^2), 144 (12^2), 121 (11^2), 101. The next square should be 10^2 = 100. Thus, 101 is the wrong term.

AI explanation

We analyze the pattern by checking the differences or underlying mathematical rules connecting the numbers. The sequence begins with 196, 169, 144, and 121, which are the perfect squares of 14, 13, 12, and 11. Following this pattern of decreasing consecutive perfect squares, the next term should be the square of 10, which is 100. Since 101 is given instead, it is the wrong term.
