Transcript text: Answer each question about the following series: $3+4.5+6+7.5+9+10.5$. What is the common difference of the arithmetic sequence on which the series is based? \[ d= \]

Solution

Solution Steps

To find the common difference of an arithmetic sequence, we need to subtract any term from the previous term in the sequence. The series given is $3, 4.5, 6, 7.5, 9, 10.5$. We can calculate the difference between the first two terms to find the common difference.

Step 1: Identify the Series

The given series is $3, 4.5, 6, 7.5, 9, 10.5$.

Step 2: Determine the Common Difference

To find the common difference $d$ of an arithmetic sequence, subtract the first term from the second term: \[ d = 4.5 - 3 = 1.5 \]
