Understanding sequences

PRACTICE PROBLEMS

Find the next term of a geometric sequence, given the first few terms

PRACTICE PROBLEMS
Solve problems such as: The first four terms of a geometric sequence are 64. -32. 16, and -8. What is the fifth term in the sequence?

Find any term of a geometric sequence, given the formula of the sequence

PRACTICE PROBLEMS
Given a geometric sequence, ether in explicit form or in recursive form, find a specific term in the sequence.
