Differences: 356-345=11, 368-356=12, 381-368=13, 395-381=14. The next difference should be 15. 395 + 15 = 410.

AI explanation

The differences between the consecutive terms of the given series are calculated by subtracting the previous term from the next term. The differences are 356 minus 345 equals 11, 368 minus 356 equals 12, 381 minus 368 equals 13 and 395 minus 381 equals 14. This creates a pattern of consecutive increasing differences by 1. Following this pattern, the next difference must be 15. Adding 15 to the last term, 395 plus 15 equals 410, which is the missing term.
