2. 8. 82.3) 823

The given sequence consists of numbers 8, 82.3, and 823. The pattern followed is that each number is obtained by multiplying the previous number by 10. Therefore, starting with 8, when we multiply it by 10, we get 80. Then, adding 2.3 to 80, we get 82.3. Finally, multiplying 82.3 by 10 gives us 823. Hence, the next numbers in the sequence would be 8230, 82300, and so on, all obtained by multiplying the previous number by 10.
