This will work if you have a to start with

For the input, take a string, with a promt like "g="
Do a sting to eqation, With the new equation as g
Prompt for a, and store it.
Then ask for the number of times you want to iterate, and store as a
variable, such as y
Set up a for end loop, use another variable, like x, start at 1, end at y,
step up 1 each time
Store the value of equation g to a
end the for end loop
display a
end the program

I hope this is want you want.
