Q: What is the 5th term of the arithmetic sequence 3, 7, 11, ...?
Solution: The common difference is 4; thus, the 5th term is 3 + 4*4 = 19.
Steps: 7
Step 1: Identify the first term of the sequence. The first term is 3.
Step 2: Identify the second term of the sequence. The second term is 7.
Step 3: Calculate the common difference by subtracting the first term from the second term: 7 - 3 = 4.
Step 4: Use the common difference to find the 5th term. The formula for the nth term in an arithmetic sequence is: first term + (n - 1) * common difference.
Step 5: Plug in the values: first term (3) + (5 - 1) * common difference (4).
