Explanation

The differences are: 131-119=12, 155-131=24, 191-155=36, 239-191=48. The differences are multiples of 12. The next difference should be 60. 239 + 60 = 299.

AI explanation

The differences between the consecutive terms of the series are 12, 24, 36, and 48. These differences are consecutive multiples of 12. To find the missing term, add the next multiple of 12, which is 60, to the last given term of 239. The sum of 239 and 60 is 299.
