Directions: Read the data carefully and answer the following question. The following table shows the number of candidates visiting three colleges (A, B, and C) as exam centers over three years (2020, 2021, and 2022): | College | 2020 | 2021 | 2022 | |--------|------|------|------| | A | 45 | 52 | 60 | | B | 38 | 47 | 44 | | C | 42 | 50 | 58 | In the following number series, a wrong number is given. Find out the wrong number: 6, 14, 22, 36, 50, 66, 84
- 36
- 66
- 22
- 6
Correct answer: 36
Solution
The differences are 8, 8, 14, 14, 16, 18, which are not consistent with a clean pattern. Replacing 36 with 30 gives a smoother progression of differences. Therefore, 36 is the wrong number.
