122

- Let's examine the series: 35, 50, 63, 80, 99, 122.

- Check the differences between each of the numbers:

- 50 - 35 = 15

- 63 - 50 = 13

- 80 - 63 = 17

- 99 - 80 = 19

- 122 - 99 = 23

- The differences are 15, 13, 17, 19, 23.

- The pattern increases roughly by 2 each step: 13, 15, 17, 19, 21.

- 80 is incorrect because it breaks this pattern. It should be 82 instead.

- Therefore, option 2 is the correct one.

80 is the wrong number in this series.
