Explanation

Among the numbers 35, 49, 50, 63, and 140, the number 50 is different because it's the only even number. All the other numbers (35, 49, 63, 140) are odd numbers.

AI explanation

35, 49, 63, and 140 are all multiples of 7 (7×5, 7×7, 7×9, 7×20), while 50 is not divisible by 7. The odd one out is identified by testing each number against the shared property (divisibility by 7) that connects the other four.
