A Correct answer
Explanation

Differences: 131-125=6, 143-131=12, 161-143=18. The differences are multiples of 6. The next difference is 24. 161 + 24 = 185.

AI explanation

The differences between the consecutive terms are consecutive prime numbers. The differences are 6, 12, and 18, which correspond to the sequence of multiples of 6. The next difference is 24, so adding 24 to 161 gives 185.
