Explanation

The differences are: 108-101=7, 132-108=24, 190-132=58, 299-190=109, 475-299=176. The pattern of differences is not immediately obvious, but 475 is the outlier in the growth rate compared to the previous terms.

AI explanation

The differences between consecutive terms are 7, 24, 58, 109, and 176. The second differences between these numbers are 17, 34, 51, and 67, where 67 breaks the established pattern of multiples of 17. Following the pattern, the second difference should be 68, making the first difference 177, and the final term should be 476. Therefore, 475 is the wrong term.
