This iteration worksheet contains varied and extensive practice in rearranging equations, choosing or confirming iterative formulae rearranged to original equations. Learners will use iterative formulae to find different values for x and use these to find estimates for solutions to equations as well as showing that quadratic equations have roots between two given values.

There is a section that looks at iteration and population models where students will use a given iteration formula to predict an increasing population and use population numbers to create an iteration formula in order to predict numbers in a decreasing population.
