Explanation

Pattern: +3, *2, +3, *2, +3, *2. 5+3=8, 8*2=16, 16+3=19, 19*2=38, 38+3=41, 41*2=82.

AI explanation

The series follows an alternating pattern of adding 3 and then multiplying by 2. Starting from 5, adding 3 gives 8, and multiplying by 2 gives 16. Applying this alternating pattern to the last number 41, you add 3 to get 44, and then multiply by 2 to result in 82.
