Let's represent the unknown number as \( x \).
According to the problem, the equation can be set up as follows:
\[ \frac{8 + x}{3} = 6 \]
To solve for \( x \), first multiply both sides of the equation by 3:
\[ 8 + x = 18 \]
Next, subtract 8 from both sides:
\[ x = 18 - 8 \]
Simplifying that gives:
\[ x = 10 \]
Therefore, the number is \( 10 \). However, it appears that this value is not in the response options you provided.
Please review the problem or the options to ensure everything matches correctly. If the sum was meant to be different, or if I misunderstood the equation setup, let me know!
