    Geometric Sequence (Only 4 terms and their sums are given)

    Using the elimination process for solving systems of equations: ##ar^{6} + ar^{7} = 5832## ##ar + ar^{2} = 24## ##r^{5} + r^{5} = 5808## ##2r^{5} = 5808## ## r^{5} = 243## ##r = \sqrt[5]{243}## ##r = 3## Substituting ##r = 3## into the previous equation: ## ar + ar^{2} = 24 ## ##a...
