Finding the unknown terms of geometric sequences

Method
  • Work in pairs.
  • (a) Work out how the unknown term m of the geometric sequence 3, m, 27, ... can be found, and find it.
  • (b) Work out how the unknown terms of the geometric sequence 2, \( m_1 \), \( m_2 \), \( m_3 \), 512, ... can be found, and find them.
  • Discuss the solution of each part in your pair.
  • Present your conclusion to the class.
Discussion
  • How can the unknown terms of these geometric sequences be found?
