Question
If z_k = 6, and z_3=15, what is z_(k+2)?
Expert Solution
Step 1 Introduction
Since Zk=6 and Z3=15 and the common difference between each term in the sequence is 9, we can use the formula: Zn = Z1 + (n-1)d, where n is the position of the term, Z1 is the first term and d is the common difference.
