Solve the problem.
Write (in the same base) the counting numbers just before and just after 3246 seven.
$165_{\text {seven }} 166_{\text {seven }}$
$3254_{\text {seven }}, 3250_{\text {seven }}$
$3245_{\text {seven }}, 3250_{\text {seven }}$
$3245_{\text {seven }}, 3247_{\text {seven }}$
Question 2
Answer
\(\boxed{3245_{\text {seven }}, 3247_{\text {seven }}}\)
Step 1 ：The problem is asking for the numbers just before and just after 3246 in base seven. In base seven, numbers are represented using digits from 0 to 6.
Step 2 ：Therefore, the number just before 3246 in base seven would be 3245 and the number just after would be 3247.
Step 3 ：So, the numbers just before and just after 3246 in base seven are \(3245_{\text {seven }}\) and \(3247_{\text {seven }}\).
Step 4 ：\(\boxed{3245_{\text {seven }}, 3247_{\text {seven }}}\)
