Activity 1
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
