Finding the General Term or Nth Term Formula

Learners will be able to:

• Identify the characteristics of an arithmetic sequence and explain how it can be expressed as Tn = Dn + C. • Calculate the value of D (common difference) in an arithmetic sequence given a specific example. • Develop a general term formula for an arithmetic sequence using the formula Tn = Dn + C, with D being the common difference. • Solve for the constant term C in the general term formula by substituting a known term into the equation. • Apply the general term formula to find any term in an arithmetic sequence.
