Write variable expressions for arithmetic sequences
Write variable expressions for arithmetic sequences
What you'll learn
- Identify the common difference in at least 4 out of 5 given arithmetic sequences.
- Write a variable expression (e.g., an = a1 + (n-1)d) to represent the nth term of an arithmetic sequence, given the first term and common difference, in at least 3 out of 4 examples.
- Apply a variable expression to find a specific term (e.g., the 10th term) in an arithmetic sequence, demonstrating the correct order of operations in at least 2 out of 3 problems.
- Explain in their own words how the variable expression relates to the pattern of adding the common difference repeatedly in an arithmetic sequence, demonstrating their understanding in a short paragraph.
