Explanation

The differences between consecutive terms are 35, 43, 51, 59, 67, 75. These differences increase by 8 each time. Adding 51 to 138 gives 189.

AI explanation

The differences between the consecutive terms follow a pattern of consecutive odd numbers. We have 95 minus 60 is 35, 138 minus 95 is 43, the next difference must be 51, then 248 minus 189 is 59, and so on. Adding 138 and 51 gives the missing term 189.
