IterationList Command

IterationList[ <Function>, <Start Value>, <Number of Iterations n> ]

Gives you a list of length n+1 whose elements are iterations of the function starting with the start value.

Example: After defining f(x) = x^2 the command IterationList[f, 3, 2] gives you the list {3, 9, 81}.
