Vectors - Ratio Theorem and Section Formula

Vectors - Ratio Theorem and Section Formula

With respect to the origin \(O\) , the position vectors of two points \(A\) and \(B\) are \(\left( \mathbf{i}+\mathbf{j}-2\mathbf{k} \right)\) and \(\left( -2\mathbf{i}+7\mathbf{j}-\mathbf{k} \right)\) respectively. \(C\) is a point produced on line \(AB\) such that \(5AB=2AC\). Find the position vector of \(C\).
