Correct answer: B

To solve for the wrong number in the series, let's examine the differences and the underlying pattern of the numbers: 145, 122, 92, 82, 65, 50.

Step-by-Step Analysis
Analyze the structure:
Each number in this series follows the pattern (n * n) + 1, where n decreases by 1 for each subsequent term.

145 = (12 * 12) + 1

122 = (11 * 11) + 1

101 = (10 * 10) + 1  (This should be the third number)

82 = (9 * 9) + 1

65 = (8 * 8) + 1

50 = (7 * 7) + 1

Identify the wrong number:
Comparing the pattern to the original series, the third number is listed as 92 instead of 101. Therefore, 92 is the incorrect term.
