8. (6 points) There is a table of natural numbers from 1 to 100. In two adjacent rows, take 3 consecutive numbers each, and enclose them in a box as shown in the figure. The sum of these 6 numbers is 108. If on this number table, using the same method, the sum of the 6 numbers enclosed is 480. Then the largest number in the box should be . $\qquad$
【Solution】Solution: Let the number at the bottom right corner be $x$. According to the problem, we have:
$$
\begin{array}{c}
x+x-10=480 \div 3 \\
2 x=170 \\
x=85 .
\end{array}
$$

Therefore, the answer is: 85 .
